Heyyo,
I suggest for waypoints, to get my waypoints. I make great E[POD]bot waypoints, and since IvPbot's also based off of PODbot, they work with Ivpbot too.
)
Actually, for E[POD]bot, I had to remake some waypoints cause some old ones weren't entirely compatible with the bot, and caused crashes on round restart. So sometimes I had to delete the .pwf files, and make my own waypoints.
Overspawning? no, it shouldn't be enough to kill off the computer, but it will kill off any extra players at random (could be bots, could be you. Most likely you, dunno why, maybe cause players spawn 1st.
)
What I'd do if I were you is find one of them spawnpoint editing things, and give it a go. I think PMB made one, check out his RACCbot site, and check in the downloads under "other projects." If he hasn't, then look through google for "spawnpoint counter strike" or something like that.
