a question abouth Counter-Stike PC game

Im having trouble adding maps. I want to play in the cs_deathmatch map but all i can find are maps without waypoints(you cannot add bots). I can also find waypoints for cs_deathmatch but I cant find any guides to do so. In short:
1. How do you add maps with or and waypoints?
2. While were at it, what is the latest version of CS for XP?

unsure on the map side...there are 3 versions of CS: Counter-Strike 1.6, Condition Zero, and Source, the latest is source.

uhn, Im usning CS 1.6, since i dont have a large amount of RAM, it lags when i add more than 8 players. woot!
