I have a working dedicated server in my computer, but I am having a lot of issues and difficulties with it and/or SourceMod and MetaMod, I installed both of them, but I still can't load my plugins

Another thing is that I would like to know these things:
* How to disable people from pushing other other people
* How to make every class have the same speed, the same as Pyro's
* How to disable weapon effects (+speed, +health, etc.)
* How to disable Medics from regenning heath
* How to unable Spies from cloaking
* How to unable Scouts from double-jumping
* How to make everyone use their melees
* How to disable Ullapool Caber jumping
* I will add something here if I remember something else
If you want, you can give me a folder with all the server files, I think it would be the best way to help me. PS.: Whoever helps me will have he's/her's Steam profile name in the server's MOTD!
