ya, cs is probably one of the best games to get accustomed to fps on the net with.
or if you like ones that aren't realistic, try out Team Fortress Classic. it's on the same engine as counterstrike.
if u want a wide array of games, look here:

Valve Complete Pack
Games included:
Counter-Strike
Counter-Strike: Condition Zero
Counter-Strike: Source
Half-Life
Half-Life 2
Half-Life 2: Deathmatch
Team Fortress Classic
The first 3, however, are just different remade versions of the same game. Source is the newest, with incredible graphics...still a growing fanbase. CZ has less players, but has incredible graphics for an older game. CS, the original, has the most players, but the least good graphics.
HL2 and HL2:DM are both great games. If you've got a nice vid card, buy em.
TFC is a classic game that everyone should play. It just rocks as compared to the realism in CS.
On their site, you can buy each of those games individually, or you can purchase them in packages...take your pick...
if your total purchase ends up being more than 80$, just buy the complete game set from the link I gave you above..
