Wolfeye - my suggestion would be to find a local community college or art school which offers a basic photo class with darkroom. You will get a chance to work in a darkroom for a few weeks and figure out what things you like and don't like. Also, spend some time here in APUG looking at the darkroom portraits - ton's of good ideas on darkrooms in there.
As far as equipment acquisition, buy used, and look for stuff that is local. You can pay more to ship a large enlarger than it costs to buy it, so finding one that you can pick up is a big plus. I would go for an enlarger that is one step larger than the size that you are using - so for 6x7 I would get a 4x5 enlarger, negligable extra cost, more versatility.
I would stick with one of the common enlargers - Beseler, Durst, Omega because it is easier to find bits and pieces for it. Personally my darkroom has two Beseler 45 chassis in it, one with the Beseler condenser head, one with an Ilford Multigrade 600 system - many parts are interchangeable, when I need something for the Ilford system, it is difficult to find, and expensive to acquire.
When I started out with my current darkroom, I bought the enlarger locally (well, about 100mile drive to pick it up), and what I got was a complete darkroom that someone was selling - the little stuff that the seller just wanted to get rid of would have cost me more than what I paid for the enlarger (Archival print washer, print dryers, paper safes, safe lights etc). I have since bought two complete darkrooms full of equipment, much of which I have sold off again, and choice pieces I have kept because that is what I really wanted - One example was a darkroom which was listed on Craigslist - the big print item was the Beseler 23CIII with dicro head, and he wanted $500 for the enlarger, reading the fine print there was a bunch of other stuff that he was throwing in, including a Jobo CPP-2 processor and a four blade 16x20 easel, both of which I still have and use, the enlarger was quickly sold again.
