To answer both of your questions;
1) Gloves: Yes, too much padding can be a problem. As you ride, the padding compresses, and is slightly redistributed so that it puts pressure in all the wrong places, such as the ulnar nerve (if I recall correctly). My gloves are the Pearl Izumi Gel Vent. I got them for the ventilation, but as a bonus, they aren't padded as such--they have a flexible plastic thing on the palm that's vented and provides a bit of cushioning, but doesn't compress.
2) The saddle problem might be compounded by the core strength issue, which is probably fairly common when riding an aggressive bike. I recently had my "endurance geometry" bike fitted, which resulted in a more aggressive posture. The first couple rides were really painful in the saddle area, even with a saddle I had previously found comfortable. I've been not-terribly disciplined about doing some core-focused yoga, and it's been a lot better. Not perfect, but better.
On the saddle fitting front. You might want to make yourself your beverage of choice while reading this: http://http://forums.teamestrogen.co...ad.php?t=39475
At least I don't leave slime trails.
