I've got the 3.5 core books and I was wondering what other books would anyone here reccomend for someone that's been out for a few years (I pretty much got out when 3.0 came out). Thanks.
As someone who hadn't played D&D for over a decade before deciding to run a 3.5 game for my group (we generally played other role-playing games), I'll toss out a few suggestions:
1) I agree with the idea of getting a low-level adventure, though I'll broaden the suggestion to any low-level adventures or even any adventure, actually, be they modules or campaign books. That will help give you a good idea of what 3.5E monsters look like at various challenge ratings and and idea of what they can do.
2) If you have a computer with a decent amount of memory (PC, Mac, or Linux) and are at least a little computer savvy and willing to figure things out, take a look at PCGen at
http://pcgen.sourceforge.net/. It's free software for creating characters and includes data from the SRD, which is most of the core material. It produces pretty PDF character sheets that calculate all of the modifiers, limits, spell lists, and such for you. It will help you know if you are doing things right during character creation. As a warning, the software is quirky and can be difficult to use at times, but the results can be great and the price is right.
3) Take a look at the Hyptertext d20 SRD at
http://www.d20srd.org/. In some situations, such as looking at spell lists to see what a magic using character can do at a certain level, the ability to click through on an item in the rules to see the full description or or explanation of the term can be an incredible time-saver. Again, the d20 SRD contains most of the important material in the core books as well as Psionic and a few other things.
I'm not sure that you really need books full of more spells, more prestige classes, or more feats until you've learned the ones in the core books. So I think that's pretty much it, thought the Expanded Psionics Handbook is pretty nifty, if you want to go in that direction. If you are planning on GMing, I've got some additional suggestions.
