Gloves - for those allergic to latex, use Nitrile (they're generally available at auto part stores if not elsewhere - as petroleum products & acids tend to get throught latex).
Reflectors for 96W - I wouldn't use the reflectors from the fixture unless they're good ones. If they're flat pr dull, get replacements (and any extra clips, standoffs, endcaps etc) from AH-Supply. Their reflectors are awesome.
If you have not purchased said fixture yet, I'd go MH w/ my upgrade $. In the long run, I think the bulbs are a little cheaper.
