Here's a list of general areas around the map, and their coordinates.
If you're going for a classic 317 revision, I reccomend Delta, Hyperion, or Allstar base. Allstar is for people who have never coded before, and Delta is a bit more complicated. Allstar has many defects though, such as many bugs, easy to cheat/dupe/"hack", also most Allstars don't come with antiSYI or antiNull, as where Delta does.
If you decide to use allstar, here is a good client, and the original source.
Downloading - AllstarScape.rar @ UppIT - Source (Allstar V2.0)
http://**********/v/6ZGPZI6B - Client (StabbingScape Open Source Client v2.2.7)
Delta sources and clients may be a bit more annoying to find. I suggest just using Allstar for starting out. Best of luck, and don't forget to Rep if I helped!
EDIT: Oh, and I can personally vouch for both of these download links as i've used both in the past.
