I can help you with the binds. Go to the original config_mp, copy the binds section from it and replace it on the boosted config_mp. So for me it would look like this
(these are the original keybinds from the original config_mp)
unbindall
bind TAB "+scores"
bind ESCAPE "togglemenu"
bind SPACE "+gostand"
bind 1 "weapnext"
bind 5 "+actionslot 3"
bind 6 "+actionslot 4"
bind 7 "+actionslot 2"
bind A "+moveleft"
bind B "mp_QuickMessage"
bind C "togglecrouch"
bind D "+moveright"
bind E "+melee"
bind F "+activate"
bind G "+frag"
bind Q "+smoke"
bind R "+reload"
bind S "+back"
bind T "chatmodepublic"
bind W "+forward"
bind X "+actionslot 1"
bind Y "chatmodeteam"
bind Z "+talk"
bind CTRL "toggleprone"
bind SHIFT "+breath_sprint"
bind F1 "vote yes"
bind F2 "vote no"
bind F3 "toggleview"
bind F10 "acceptinvitation"
bind F12 "screenshotJPEG"
bind MOUSE1 "+attack"
bind2 MOUSE1 "+vehicleattack"
bind MOUSE2 "+speed_throw"
bind MWHEELDOWN "weapnext"
bind MWHEELUP "weapnext"
instead of this
(this is the boosted 1, I removed all the chat binds and after that thought of the new method instead of editing this.)
unbindall
bind TAB "+scores"
bind ESCAPE "togglemenu"
bind SPACE "+gostand"
bind 1 "weapnext"
bind 5 "+actionslot 3"
bind 6 "+actionslot 4"
bind 7 "+actionslot 2"
bind A "+moveleft"
bind B "mp_QuickMessage"
bind C "togglecrouch"
bind D "+moveright"
bind E "+melee"
bind F "+activate"
bind G "+frag"
bind Q "+smoke"
bind R "+reload"
bind S "+back"
bind T "chatmodepublic"
bind W "+forward"
bind X "+actionslot 1"
bind Y "chatmodeteam"
bind Z "+talk"
bind CTRL "toggleprone"
bind SHIFT "+breath_sprint"
bind F1 "vote yes"
bind F2 "vote no"
bind F3 "toggleview"
bind F10 "acceptinvitation"
bind F12 "screenshotJPEG"
bind MOUSE1 "+attack"
bind2 MOUSE1 "+vehicleattack"
bind MOUSE2 "+speed_throw"
bind MWHEELDOWN "weapnext"
bind MWHEELUP "weapnext"
Hope I helped.
