Welcome!
There are many great resources, and I advise you to check them all out:
How to Brew (first edition is free online, but the 3rd edition is a nice reference to have on hand)
Joy of Homebrewing
Homebrewing for Dummies (it's actually very good)
This site is probably the best place to get up to date information and a variety of opinions on all sorts of homebrewing and related activities.
www.basicbrewing.com and
www.thebrewingnetwork.com both have very good podcasts and video podcasts to check out.
First and foremost, though, is to check out the stickies at the top of the "Beginners" forum. There is a wealth of information at the ready. Remember there are a variety of ways to do most things in homebrewing, but a few things will help get you making great beer quicker:
1. Sanitize! Proper cleaning, followed by a proper sanitizing is a must! (I personally recommend StarSan for it's ease of use and re-usability if mixed with distilled water)
2. Fermentation temps! I try to hit the lower end o the yeast's optimum range. You can get the information on the yeast manufacturer's website. Try to keep it constant until at least the fermentation has slowed down and the krausen (foam) has dropped. (few days to a week or so)
3. Pitch the proper amount of yeast. 1-2 packets of dry depending on the starting gravity. Make up a starter for liquid, and make enough depending on the OG as well.
4. RDWHAHB!
