I posted some example pics of trekking bars on a mountain bike page 3 or something like that?

You should also look up a thread by Hefzilla where she installed trekking bars on her mountain bike recently.

Otherwise, Sarah gave you a ton of good info.

With gloves - sometimes they contribute to your hands going numb, I can only use pearl izumi gloves if I rip out the padding.
