I've had the pleasure of meeting Ian 'Stargazer' at Wonderfest, and he always does great work on his kits. Since this is your first resin kit, do bear in mind that while the kit instructions are short, they are accurate 
and worth reading!
The real key to success with any resin model is that they have to be cleaned up by you. No joke - if you don't clean the heck out of that model, paint will not stick to it! Many of us who build resin kits have favorite cleaners:
Simple Green
Purple Power (used to be Castrol Super Clean)
Soft-Scrub
Dawn Liquid soap
I will use an old (retired) toothbrush to scrub the model down with cleaner, and then another old retired toothbrush and clean water to clean the soap off with. Obviously, use eye-protection and some disposable gloves when you do this. It protects you, and modeling is supposed to be fun, not about hospital trips. Allow the parts to air-dry overnight.
I then prime all the parts, usually with Krylon fast drying primer. Then build and paint. Ordinary glues will not work on resin, so you must use either superglue (CA glue) or 5-minute epoxy glue. Assuming that you dry-fit all the parts first, you want to adjust the fit by sanding.
Sanding resin is rather hazardous as it creates really small - virtually invisible - dust particles that you will inhale and once in the lungs, it doesn't come out. Bad. So wet-sand, or, use ventilation that will get the particles away from you and trap them in a filter. Like a paint booth set-up.
