As far as the books go, Ebay is always a good route of action. If you don't want to mess with that route, start by getting a general idea of the books values. The following links will get you started.

granted you may not want to spend alot of time, but a little research can go along way so you don't undercut yourself.
There is also another great site.
www.craigslist.com. Some of the benefits are free listing, wide audience, & quick response. This avaenue would also be suitable for your alsums as well.
Specifically on the albums, I just sold a lot of 700+ a couple of months agao. Initally, I tried to calalog them, but after the first 200 I lost interest pretty quick. I pulled the more interesting ones, did a price check, and sold them on Craigslist. Initilly, I sold them for a couple of bucks each, than lowered the price over the next few weeks.
To research market value on your records, go here:
http://www.popsike.com/
This will acces past and present auctions for recent sale prices.
Oh, and since you are in the LA area, this store is known worldwide for buying and selling albums.
