As far as I know, the AX15 has an early and late pilot bearing. You'll need a pilot bearing (or bushing) that fits the AX15 that you plan on installing. It's always a good idea to replace the pilot bearing anyhow, whenever you have the transmission out.
If you have the external slave bell housing, all that you need to do is bolt your AX15 to it.
As far as I know, the BA10 and the AX15 transmissions are interchangeable except for the pilot bearing and the external slave AX15 uses a longer front seal retainer that should have come with your internal to external slave cylinder kit.
If you're using an AX15 from a Cherokee (XJ) you'll need to "clock" the rear of the transmission so that your transfer case won't hit the tub.
"Clocking" the transmission includes using a jig to drill new holes at about 15* from where the Cherokee transfer case bolts. It sounds like that won't be an issue with your trans/TC from a Wrangler.
Other more knowledgeable posters may have more to add or may even contradict what I state above. I'm planning to do the same swap later this year, so I've done some research and have the AX15 trans to install but haven't bought the external slave parts yet.
Good Luck, L.M.
