Sure can, go to fishgeeks.com , sign up as a member and get yourself on the forums there. They will tell you absolutely everything you need to know, from the best (and worst!) fish, to how to avoid New Tank Syndrome - that thing where novices overload the tank and lose half the fish, _then_ find out what they did wrong :) the best fishkeepers have done it (myself included, i'm ashamed!), but the guys and gals at fishgeeks can talk you through setup to stocking, and you should be able to avoid most, if not all, the common pitfalls of a new tank.
Apart from that, the best advice I could give you is this - be patient! And be aware of the people in the fish shops - it sounds harsh, but sadly a fair few of them are painfully clueless about fish. No offense meant to all the clue-ful people out there!
Good luck!
