I'm no expert as I don't collect them, but I'll try to help.

1. Walmart does carry them, as does Toys R Us. TRU often has exclusive versions, too. Otherwise the 3 you listed are good.

2. I check stores once a week. Sometimes more. It seems that Marvel Legends are cranking them out, so once a month would likely mean that you'd miss entire waves. If you have the above stores close to you, I'd check at least once a week. And, don't be afraid to ask the stores when their shipments come in and if they have anything in back that has not been put on the shelves yet.

3. A local comic shop might help, or just good ol' Google.

4. Not that I know of. I check Amazon and eBay for going rates. And, keep in mind, these fluctuate with frequency, so checking often is the best idea.

Buying figures in person is a lot trickier, but to me, a lot more rewarding. I'm a freak when it comes to paint applications, so I hate gambling with online purchases.

Welcome (back) to the world of toys. Good luck and happy hunting!
