Anyone play CS:Source?

[Nuggs]

So really stupid question incoming. I played a shitload of CS 1.6 but never played much CS Source. I've been getting back into CS Source recently and forgot how much fun it could be.

One thing I can't figure out is the scoreboard (yes I searched google but it's all cs:go results). What do the stars and medals on the scoreboard mean? There doesn't seem to be a consistent pattern to them and I can't figure it out. 

Stupid question two: do bots in Source display a ping? All bots on goldsrc display a ping of 0 but I'm not sure if that's the case for Source as well. I want to make sure I'm playing low ping bastards and not bots as the servers I play on almost everyone has a ping of 15
