Hi To-nee-t,
Welcome to PCHF. We have a wonderful staff of techs with a wide variety of skills, and I am sure that we will be able to help you resolve this problem.
First of all, it sounds as though your keyboard needs to be cleaned. The fact that some of the keys are sticking sounds more mechanical than software related to me. I would highly suggest removing the keys, using q-tips and isopropyl alcohol to clean under the keys and the keys themselves.
In order to disable your keyboard, you will need to go into your Device Manager locate the two keyboards listed and under properties for the main keyboard, click on disable in this profile.
Hope that helps,
TTFN
LGW
