server issues ?

[Drocona]

No you didn't search good enough:

1. missing particles is a common error, it always does it, can't be fixed but then again it doesn't do anything bad either except spam the console at startup

2. skill1.cfg can be ignored
3. server.cfg has to be in SRCDS\<modfilder>\cfg
4. Only needed if you want a map specific configuration

These and all your questions have been asked numerous times, I suggest looking in the tutorials section on this forum to get an idea about how to work this all, for the rest, just use the search function an google.
