There are multiple parts to fiberglass. Fiberglass cloth, Fiberglass mat, and Fiberglass Resin. The cloth is very easy to shape, so it is the first piece you use. You then mix the resin, and cover the cloth in it. You can then wait for it to dry, and then use the Fiberglass mat and more resin; or you can apply the mat directly to the still wet (or tacky) Fiberglass mat/cloth, and add some resin.
When it comes to working with styrofoam, you can cover it with aluminum foil it keep the Methyl Ethyl Ketone from making contacting it, which will stop the chemical melting. The aluminum foil has worked well for me, and I have had nothing effected during the process. See my kick panels made using fiberglass, bondo, and matching vinyl:

One benifit to Fiberglass over Carbon Fiber is it isn't as nessisary to vacuum cure it. Carbon fiber works best when it is placed in a vacuum sleeve while curing. The same vacuum process is done for Fiberglass, but only when the finished product has to be air and water tight (ie boat, and airplane bodies).
With fiberglass you HAVE to wear thick gloves, otherwise your hands will be filled with annoying glass splinters by the time you are done. They really s*ck because you can't see them to pick them out, and washing your hands doesn't get em' out either, so wear gloves!
Hope this helps,
