If you use epoxy then cloth is appropiate. It will keep weight down and use less resin.

could i just coat the polystyrene with epoxy(no cloth)then do the next layers with mat and vinyl

I assume you are talking about vinylester resin. It won't adhere well to epoxy. Why don't you want to laminate cloth with epoxy?

I will get a lot of arguments on this statement... The best epoxy is the the one you are use to using. Some are better on the environment (less voc) Some work better in tropical climates and some better in colder climates. I would bet money at one time clear coat was the best in the world but when they sold out and I had to have epoxy yesterday I had to try something new. Guess what? it works. Now do you want slow or fast hardener ? 2 to 1 or 5 to 1. It all depends on your personal preference.
And there is the old saying " you get what you pay for"
Good luck
