How can I: Copy a generic form and then make changes.

Question

Hello:
 
I have a generic form that has most of the standard changes that I need in it. I would like ot copy it into my project and then change a few things in it.
 
What would be the best and simplest way? I tried that 'Inherited Form' thing, but it locks all the objcets on the form. Am I doing something wrong or should I not use that?
 
((Hope I explained it correctly... Also I am a super newbie to this stuuf, so dont assume I some stuff.))
