Just got my first kit!

I have a few questions before I start on it.

It’s a Revell Kit, did not come with glue/paint.

Where would I buy the right paint? I live in Canada. Is Michael’s the right place to look? Is there a kit that would include paint specifically for the kit?

What glue is best to use? Where should I buy it?

I watched a few videos online, and it’s looking like everybody uses airbrush. Will I get okay results if I hand paint?

Is there a varnish/finish I should spray or paint on after I’m done?

Any extra tips and tricks for a first timer?

I appreciate all the help :)
