For print I'll generally go with Comic Buyer's Guide as a primary. They've been around since the early 70s and tend to be pretty good. Wizard gives you a cursory look at the really popular stuff - it's kind of like fast food. It's a quick fix but not a lot of nourishment. Having said that, I subscribe...
Beyond that, Geek Magazine has comic reviews as does some periodic coverage in Entertainment Weekly. SFX mag is about to be published domestically, and they have a surprising amount of comic coverage.
Newsarama is very popular, CBR is very good.
I would probably begin with going to creator sites and checking out their forum. That way you can interact with people that share some of your similar tastes and get recommendation there. Just like you did here!
I think Millarworld (Mark Millar's site) is one of my personal favorites. Warren Ellis' Whitechapel board is cool, too.
Hope that helps a bit...I think the next topic should be "Where do you find the best online deals for graphic novel purchases?"
