One source of info: www.shimano.com Select bicycling and North America and then select technical and rummage through the spec sheelts till you find your shifter. They have pdfs on the site for all their tech lit which should explain what you need to know.
Somewhat more generalized is www.parktool.com under the Repair tab is an extensive writeup of how to fix things on bikes, good tech base.
FWIW SRAM, FSA, Campy et al have similar repositories of tech data on their respective web sites.

gripshifters are tough, and you'll probably have to pull the grip off to get it done. but yeah check out the park tool website

You need to remove the grip, the part of the shifter that you actually rotate in order to shift, and then slide the cable out of the run it occupies inside of the shifter. While you're doing that be very careful not to dislodge or lose the small metal spring (just a bent ribbon of metal, not a coil spring) inside the shifter. If it comes out it is a big pain to get it back in again. It's possible, just annoying.
To install a new cable, you perform the removal in reverse and then slide the grip back on.
Gripshifters are a pain to work on, but you should go for it. Good luck.

SRAM shifters which I have used differ in that they have a port whose cover is removed. Older versions
have a nearly invisible allen screw buried there whose removal reveals the cable end which can then be popped out through the port. Newer versions have a retention leaf spring that is pried up and the cable end is then popped out. No further dissassembly needed. My R shifter began to act up a few months ago and needed 2-3 detent over shift to accomplish a shift. Nashbar was selling SRAM Attacks for $25 and I replaced the shifter resolving the problem, but the new shifter is 'reversed' from the old and muscle memory takes longer to retrain. Autopsy of the old shifter shows they are extremely simple constructs:
structural plastic, two pieces, one short pivoting leaf spring that operates the detents and not much more. There was no obvious abnormality in the bad shifter, which had lasted 13kmi.

actually, i looked into it and the grip doesnt even have to be touched. one thing on the shifter pops off and the cable is revealed. so i pulled it out and tried inserting the new one, but while trying to squeeze ti thru the tiny ass hole and all the guides along the body, it kept unwinding the wire. so im gunna let the repair guy install it for me when he repairs my ferailleur
