Welcome from Canada! This site is amazing, you will find all sorts of help, and friendly people willing to offer it, so dont be afraid to ask questions :thumbsup:
And I agree with with what @middleagecrisis had to say, start with the basics and tune it up as best you can and go from there. And hes right, that hard shifting may be due to a shift kit installed if your dad did some racy improvements to it.
