To use the meter, assuming it is working correct:
Align the inner dial to your desired ASA (ISO).
Point the sensitive end toward your subject. The needle should move in response to light. (You may have to depress a button on the side of the meter, if it has one.)
Rotate the large dial until the "O" on the dial aligns with the needle. You should now be able to see the various coupled combinations of aperture and shutter speed available to you. Pick the one you'd like to use, and set your camera.
Way back when I was starting to do development, I had a NIKOR Stainless Steel 120 reel that came with a loading tool, just a bent chrome metal item that let you hold the film with JUST the right bend to get it to load on the reel. At the time I got to like the SS reels as they would load even if they were a bit damp. I was using the school darkroom and so my equipment was in a locker and never got a good chance to dry.
One thing I found annoying with the stainless steel is that where the film touched the reel there was always a narrow undeveloped, Unfixed Streak. This made reading the frame numbers hard in 135 and often intruded in the actual image on 120.
These days I mostly use the JOBO 1500 Series, but they have gotten rather rare and expensive as JOBO went though a reorganization.
The Paterson compatible Plastic reels that were mentioned earlier are VERY EASY to load, and I will often use one of those with 120 if using a Paterson style tank.
If you only need to develop one roll at a time this

are also good buys and may be a touch easier to use than the Modern Patterson line, just because the Plastic cap is easier to put on and take off. (I am not positive but both these tanks are likely the same item made by A-P In Spain, although I have one that looks the same that was made in Hong-Hong.)
That tank is just a smaller version of the one I linked to for you. It will work well, but it won't let you develop with two reels set to 120 size at the same time.
The Paterson reel included with it is good. I just find that the reels I recommended, which are most likely the ones included with the two tanks Charles recommended, are slightly easier to load with 120 film. They have wider flanges on the input end, which help a bit.
If you need to, you can use the reels I recommended in the tank you bought.
The one thing to remember with Paterson tanks is that when you put the lid on, seal it all around, press in the middle of the lid and slightly lift up the edge until the air comes out (sort of like the way the 'Tupperware' thingy worked). Otherwise it might leak on you when you invert it, but this way it won't.
Also, the best advice I've ever heard about plastic reels is that before you load them, take them apart and run a pencil around the spirals, the extra graphite makes them load so much smoother (especially important for 120).
If you are going to use Paterson reels for 120 here is a tip to help load the film.
Cut a piece of the film box to be the same width as 120 film and about 2 or 3 inches long.
Before you go in the darkroom slide this piece of card along the reel tracks into the beginning of the reel but not past the little ball bearings. Now when in the darkroom take your film and slide it along the card until it is past the ball bearings and pull in a bit more then remove the card and load in the normal way. You see the card acts like a guide and makes those springy films easier to get started.
I most often reverse curl the first 1/2 inch or so of my film before loading to help with the springiness.
I still have the same bit of card I cut out of a Fuji box a couple of years ago, I only replace it if it gets lost or banged up.
Paterson tanks are light sealed by the funnel insert, not by the lid. Unless of course there are Paterson systems I don't know about. But then how would you be able to add chemicals if the lid were the light seal???
This idea sounds like a beauty.The extra width and thinner base of 120 frequently gives me grief in trying to start 120 on a Patterson reel.
Even if you go plastic, practice in the light first. You can still run into problems. Practice a lot. You want it to be committed to memory, and nearly automatic, before you do it in the dark(bag). The idea is to understand what is going on with either type of reel, how to tell if something isn't going as it should, and how to do it without looking.
Truzi, This is sound advice, and truth! I have unfortunately seem to have a used system, that seems to be an incorrect size, as it won't load the 120 properly, no matter how I try, or view it! I assumed it were the right reel when I purchased it, but, since I had no clue, I used it anyhow, with tons of overlap, and bending! When I tried it again in light, I noticed that the size of the 120 surpassed that of the reel!
Are you saying that the film was too long for the reel, or too wide for the reel?
I was thinking 127, but with 14mm difference you'd definitely know it was the wrong size. And the other films listed on the wikipedia page for 120 (105, 117, 620) are all just slightly larger, so a reel for them should be, if anything, too big for 120, not too small.
If it's only just (ie 1-2mm) too small for 120 then I'm stumped, maybe someone swapped around bits of plastics until one fit together, even though they weren't made for each other?
Having not done this before, aRolleiBrujo may not have known how it was supposed to be. The first time I used steel I thought the film was supposed to be pushed through the same way it is ratcheted with plastic reels.
A simple cell phone picture with the film next to the reel may help us identify the reel.
