Wow, thanks! I'm glad you like my pics.
🙂 To answer your questions:
My setup is simple: Canon XTi, Canon 100mm macro, Ring Lite MR-14 EX. No tripod, as I mostly do field work and it's too much of a hassle to set up. Besides, I don't have the tripod ring, so I don't want to risk damaging the tripod thread by placing such a heavy setup on a tripod.
Here's a pic to give you an idea of the size of the lens and ring flash when attached to an XTi.
As for settings, I normally use Manual mode, 1/200, f8-11, ISO 100 and center focus point (some in manual focus). Depending on the framing I may me anywhere from a meter away to 15 cm from the bug, measured from the front of the lens

The key is to practice a lot, and have patience. On good days (3-400 pics) I usually end up with 20 that I really like, so don't fret!
