For increasing throttle resolution, if you're not big on modifying your throttle lever attaching point, you can sometimes do it a very easy and temporary way with a piece of aluminum foil crushed and pushed into the cam-shaped throttle cable groove on your throttle lever.
Just keep in mind the point is to make the gas pedal less sensitive at very low throttle positions. Make sure you pre-test it to make sure the cable stays aligned and isn't in danger of coming out of the groove, or binding. (safety)
Here's a pic to try to help with the explanation.
