Tranny time - have it done or tackle myself?

Well, had the jeep running pretty good.  Was looking forward to the fall hunting seasons and taking on a few weekend drives.  Then it started making some grinding noises on start-up.  I knew the ring gear was marginal when I put a rebuilt starter in it, but I was anxious to get some use out of it and didn't really want to tear in to the tranny just yet.  But now I guess I have to.  I've never done anything like this before, and I'm hesitant to get into something I can't finish, due to skills, tools, or both.  I figure if I had to take out the tranny to put on the ring gear, I may as well rebuild the tranny and transfer case while I'm at it.  The transmission had been shifting ok, but leaked some (not terrible).  It had been sitting for over 12 years, so the seals may have got pretty dry.  The tc would pop out of gear when letting off the throttle going down hill.  And I would guess the rear main ought to be replaced while we're at it. Money doesn't grow on trees around here, so I need to be frugal, but if this is a job an experienced mechanic could get done in a few hours, I'd almost rather pay to have it done.  (we do have a good manual transmission mechanic about 45 min away).  I don't really have any knowledgeable friends to help with the job, but I do have a couple kids that are always anxious to get their hands dirty helping dad.  Any suggestions?  How was it the first time some of you tackled a job like this?

Thanks,  Mark

The 3a transmission and transfer case were the first rebuilds of that type for me...

I think I just got the kits with the seals, bearings, and gaskets...gears were OK..

Still going strong but doesn't get hard use..

I followed these tech tips from the 3a home page....lots of help here too if you need it!

Googles
I'm in the same boat as you, not a bad wrench turner, but maybe not so great on diagnosis.  My tranny gave me trouble at the FCT, got home took it down and I noticed some issue, but I don't know if they are problems.  I just took it to the same guy, the fellow 45 minutes from here that knows manual transmissions well.  His job is to do the diagnosis and let me know just what is wrong, then I can decide if I want to do it my self or not.  I do plan on adding an over drive while its out.

Some data points - New transmission from Kaiser - $900- $1000 bucks
Re-builts from Herm the overdrive guy are available  I think I saw a rebuilt X case for about $500?
Transmission Tower - $150 at fitzpatrick - NOS

As stated, good advice and tech tips here, lots of guys willing to help.  Just a matter for me of getting the right diagnosis.

Been doing some looking, and I think I could get the tc and tranny minor overhaul kits, along with the ring gear for under $400.  And I found what seem like some really good instructional videos on YT from metalshaper that seem to be on a level I can understand.  Like you, gunslinger, I'm weak on diagnosing, especially if there would be issues greater than what the minor overhaul kits require.  Also, I noticed during his videos that metalshaper has some specialized tools that I don't have access to, and I think that may make part of the process rather difficult.
Thanks also for the rebuild thread links.  Still debating in my mind on what to do.  Wife points out the picture on our fridge that says "Be decisive.  Right or wrong, make a decision.  The road of life is paved with flat squirrels that couldn't make a decision."
