I'm going to learn fiberglassing soon and I'm wondering what do you guys recommend as well as what do you do for materials and tricks? I already know metal working and bondo so if any of those skills are useful for this application at all

You probably need to be a little more specific. What kind of project were you aiming to do? Are you planning on constructing plugs or molds? (There's lots of great books, websites and youtube videos available on fiberglassing.) Metal working and bondo skills, like all hand skills, will indirectly help though there isn't a lot you will directly take from one craft to the other.

If you are going to be doing anything with Fiero parts learn what the material is that they are made of.
For instance, the hood and decklid are SMC which you need a special resin or adhesive to bond to it.

What you need to be aware of is the dif shrink/expansion rates of SMC and fiberglass at dif temps.
Also, don't recess metal screws in SMC and then cover them, they will pop up eventually. Use nylon screws instead, they react to temp changes much like SMC.
If it's for a small repair, like a little dent or deep scratch use something like Evercoat's poly-flex and not fiberglass.
If it's for a standoff part like a custom rear, np.
If you ever need replace a big panel like a door skin, save the old one. SMC material is not that easy to find.
Work in a well vented area wiht old clothes and buy a box plastic gloves.

This subject gets a lot more complex than you would expect.
