I'll not mince words. Everyone here gave supersolid advice, I would add that a good pair of roller blades so you can literally pick up and skate around anytime wouldnt be a bad plan. If you're lookin for ice hockey, stick to that until you get a good grip because roller hockey can give newb icers bad habits and vice versa, but skating is skating for the most part. (stopping...waaaay diff.)
A more attainable goal would be giving yourself a few years if you have time for lots and lots of practice to aim for higher level in-house leagues. Playing Am or Pro... probably not happening.
This is step one.

After that, just get out and play. Practice as much as you can. If you can, go to a skate class or two, but it's by no means required.
In this case, you just need to grab the gear and get out there.
