For a plastic model, as far as adhesives go, good old tube glue for plastic kits will work fine, or cyanoacrylate (CA or super glue), or you can use epoxy if you want, but that can get messy.
For construction, that's what the instruction sheet is for, but I always dry fit (test fit) everything BEFORE I apply any glue, in case things don't fit tightly and need a little sanding or trimming to fit nice and snug/flush/tight. Other than that, it's a matter of taking your time, making sure the major subassemblies are completely dry before adding them to the other subassemblies, and checking the instructions as you go to make sure you don't miss anything.
It's also a real good idea to read through the instructions completely before you start building, and look at all of the part sprues, so you get an idea of where every part is, and where it goes - that helps avoid any ugly surprises during assembly.
