The best place to start is to click on this link and buy the electronic workshop manual. https://www.davesitshop.com/emporium...&product_id=10
Re your oil leak problem. I think you'll find your rear diff is not a Rover diff, but a heavy duty Salisbury unit. They're pretty bomb proof, but as with all Defenders it seems, with age and use comes some slop in the transmission, which tends to result in a "clunk" as you let the clutch out at each gear change.
There are a number of areas where this slop can occur, but the most common is where the axles slot into the drive flanges. It seems that a previous owner may have (wisely) replace the Land Rover flanges with Maxidrive or equivalent to reduce this transmission slop issue. Hopefully you don't get too much clunk when changing gear as a result!
Re the problems you're having with that O-Ring. Not sure why it's not seating properly, but may pay to get a slightly smaller one and have another go.
Others on this forum may have more experience in this area than I do.
When re-tightening those loose studs, did you apply thread locker to the threads? I'd suggest it would be a good idea to do so. Would also pay to check the studs on the opposite wheel, just in case they're also coming loose.
Re topping up the diff. Yes, just make sure you're parked on a level surface and fill to the point of overflowing from the filler plug. You should not need to use thread sealer here as in my experience, these plugs are tapered and if tightened properly, will not leak. Also a minor possible danger of contaminating the oil with thread sealer. (May or may not be an issue).
Once you've done that little job, then you're OK to tackle changing oil in the front diff and the gearbox and transfer case. You'll probably need a half inch socket extension with a sort of rounded end on it (Makes it able to work at a slight angle...available at any decent tool shop) to get to the Trans Case level plug and from memory you'll also need a splined socket as in the picture to get to the hard to reach level plug on the gearbox.
Will also need to get a small oil pump to pump the oil into the various boxes and diffs (again, see picture).
Good luck!

, the club had an annual workshop day, the intent was to transfer skills, by doing some common, popular tasks on member vehicles, plus the BBQ and beer of course.
