Paints are good. I use those myself. Also look into the Wicked Colors line (an alternate Createx brand) that you can pick up to some extent from Hobby Lobby, a local art store, or online via TCP Global.
For guns, I prefer my el cheapo harbor freight dual action brush, or the el cheapo harbor freight mini spray gun for doing primer / white coats (covers very quickly/easily for larger surfaces).
I also have a few other brushes (Master brand). For our purposes, pretty much any brush will do.
A few recommendations from my experience: adjust pressure / flow so that you can use the paint unthinned at first wherever possible. Thinning opens up a lot of variables that can be frustrating. I rarely thin my paints these days. The Pearlized paints are the only ones I thin, and even then only some of them require it. Others don't.
Also invest in Auto Air Sealer White. It makes for a good first coat to cover all the prefinishing you will do using automotive filler primer / glazing putty / CWF / Tamiya or Squadron putty. The acrylic paints wet differently on those different surfaces; a coat of Sealer White gives the acrylic color coat a nice even surface to stick to.
And most importantly: CLEAN THAT BRUSH THOROUGHLY after each use. Use the Restorer (good job getting it) when needed, but remember it is oily so you have to get rid of every trace of it before you can paint with acrylics afterward.
Good luck and keep us posted.
