Shifting questions, and rolling forward in park
Two questions:
1) My 98 1500 auto seems to roll forward more than it used to when I put it into park. Is this something that can be adjusted (without dropping the transmission)? What do I need to be looking at?
2) What determines how much the gear shifter needs to be pulled towards the driver to get over the "tooth" between gears and is is adjustable? Even after owning this one for a few years it seems that it is way too easy to accidentally shift into the wrong gear (which is very different from how my 97 was).

Sounds like parts of your shifting linkage needs to be adjusted/replaced.
On a level surface, with wheels chocked for safety:
Grab a screwdriver, flashlight & needle nosed pliers, go under the vehicle just behind the drivers front tire, on your back, might help to wear some clear work glasses to avoid rust/grease blobs in the eye.
Disconnect the linkage from the shifter thats on the tranny pan [usually just a cotter pin holding it in on older trucks, but not always], and have someone shift through gears while you observe the action of the linkage, then have them put the shifter in park.
By hand, go through all of the gears on the tranny shifter - They should all offer slight resistance, and make a distinct click with every shift. Put it back in park, all the way towards the front, I believe, and see if you can get the linkage pin back in the tranny shifter.
If you can't get the linkage to mate up with the shifter in that position, then something is out of whack.
You can often bend the linkage back in correct position, the idea being to have perfect sync between what the gear shifter says [park, neutral, reverse, drive ect] and what the actual position of the shifter is.
Once mated correctly in park, all other gears should also be correct.
If the gear shifter says park and it mates up perfectly with the tranny shifter in park, you have other issues which will require further diagnosis & repair.
If the tranny shifted through gears very easily by hand, offered very little resistance with no clicks, then you've found your problem.

Thanks xray. Do you think this also is the cause of the first problem as well? When I put it in park it seems to do the normal slight roll forward, then I can hear it catch on something (like it moved past the stop position and whatever was supposed to stop it) then rolls forward another couple inches.

Any vehicle will roll a bit before catching ,, It seems to me that it either catches, or it doesn't.
I can't think of anything that would make it roll more than usual, and then catch.
Hopefully someone with hands on experience in repairing an unlocking trans will chime in.
I had a truck that didn't lock, period ,,, But it was such a POS that I never bothered to fix it, and just chocked the wheels whenever it wasn't level.
