I'd be happy to take a look at your list, if you PM me. I was in your position just a few months ago. It's promising that you're going for expired domains (which at least had value to someone) rather than hand-regging a bunch of stuff, but the previous poster is right, there is a learning curve that everyone needs to go through before you really start finding valuable names.
Reading the boards (particularly the newbie threads, how to sell to end-users, and reported sales) helps, as well as checking out DNJournal's weekly sales report. That will give you an idea of the names that are actually selling right now.
You can also learn a lot by reading the major
domain blogs - I can't provide links here, but look up Elliot Silver, Morgan Linton, Chef Patrick, The Domains, Rick Schwartz, Dot Sauce, Nametalent, and most of all, Domaining.com. You can also check out my blog, which is relatively new (and linked in my signature). I'm posting articles about a variety of topics of interest to domainers of varying skill levels.
Checkout Namejet, Snapnames, Pool, Godaddy TDNAM to see what's selling.
Join Twitter. It sounds silly, but it's an excellent way to network with domainers & keep up with industry news. Do a search for "#domains" for people who have 'domain' in their handle for some ideas on how to find people to follow. If you add people, chances are they'll follow you back.
Try to not register too many names before you've learned what sells, because it'll get expensive, and you'll end up having to drop them (meaning you let them expire on purpose). You can avoid some of the newbie pitfalls by asking questions and reading everything you can.
I'd be happy to steer you in the right direction. One of the first things I did was get a portfolio review from someone more experienced. He said, "Drop the crap, keep the rest."
