So I got a Gibson Les Paul studio

I also bought with it some Zak Wylde EMG's

I read the instructions and it said to use the long pots in a Les Paul.
I get through installing it and soldering it and I notice the pots stick out way to far.
Then i notice the knobs dont stop......ie they keep turning...

Do I put in the short pots?

Also where do I ground the last remaining wire at

Hopefully I explained it well enough

Any help or tips would be greatly appreciated

Thanks much
