First question. Is it required to prewash floss before use? At least
for items that are meant to be framed with glass?

It is absolutely not necessary to prewash floss before it is used, as
long as you are using high-quality brands such as DMC or Anchor. Can't
speak for the lesser brands. I don't purchase kits, usually, and the
only other floss I have around is old Beldings, which didn't need
prewashing either.

A very few persons here at RCTN have had trouble with a couple of the
DMC threads running since the dyes were changed sometime back. If you
are going to wash your project after you have finished, you might want
to ask about here to see what people have to say about this. Even if
floss runs, rinsing numerous times usually solves the problem.

It will not be a problem for you under glass.

Second question. So far, I've only done prepackaged kits and I'm
NOT thrilled at all with the gold metallic threads that come with
those kits . . . are the problems I've been having not found with
DMC metallic flosses?

I have not liked the DMC metallic flosses that are skeined. However, I
do love, very much, the Z-threads that are wound on spools. I've used
several shades of gold and silver and enjoyed them. They wash well, but
like all metallics, don't take many washes before they begin to fray.

Can't help you with the rest of your question, nor question 3. grin
