Nice kit!
I would say that Youtube was a great help for me on in getting the basics down, as well as the processes to avoid a jammed body/lens, like mentioned above. Basic camera work is like any other mechanical camera without a light meter, if you know these things, the Hasselblad isn't terribly different from anything else really: load film, aperture/shutter speed, focus, press the shutter and advance film (wind mechanisms).
It still amazes me how many 'safeties' built into the Hasselblads and how effective they are at keeping you from inadvertently exposing your film to daylight. But, if you do something out of order it can end up in a mechanical jam, which needs a little knowledge to get out of.
With an older body, I would suggest you have a look at how the lens is functioning with the film back off the camera (camera works without a film back in place). Set the lens to a long shutter time of 1 second, then set the aperture to something like f16 (=EV of 8) and then watch the lens function from the film's perspective or the camera's back while pressing and holding down the shutter. You should see the aperture blades tighten down to a small hole and the shutter clockworks work away. Then after the 1 second exposure time, the shutter will close. You will also be able to view the 'barn doors' and the mirror movements from this position. Besides its just fun to watch all the stuff going on from this perspective. Release the shutter button, wind the body and repeat with half and quarter second shutter speeds.
The aperture and shutter actions should be crisp and immediate, old gummy oils/dirt etc could make them act differently and the pictures you take could all be at a different exposure than you set the camera to, and lead to much frustration after you get the film developed. If anything else than this happens, you may need some work done on the lens/ body. It is possible to take a video of the slower shutter speeds and then just measure the time, in video editing software, between open and close to get a feel of how accurate the lens is working, obviously there is a limitation on what you can achieve with something like a cell phone video recorder, but 1 second 0.5 second and .25 seconds should be achievable for most.
