Apparently it's pretty subjective. Personally I think the 4.10s are just adequate for the stock 32's, but people are running 33-35's and tolerating it (same for 3.21's and 33's). At least you have a 2-door, which should help your cause a little.

You will lose a little bit of power, but it will not be overly noticeable.

I have 35's on 3.21's and I am content.

I have 3.21s on 34s and I am UNHAPPY.

EXAMPLE- Just yesterday I am on the interstate, 4th gear 60 mph and tacking 2600 rpms trying to pass grandma. Sorry, grandma. Six gear does not exist for me. But I live in the foothills of the Blue Ridge Mountains so the roads here aren't exactly flat.

When I go yakking with my buddy who has a F-250, he is constantly ragging on me about having to wait for the Jeep. Granted I am no speed demon, nor do I expect a 2" lifted Wrangler on 34's to preform like one. I just hate having to fight the thing to climb hills and sticking my foot in it to get going.

Monday, I will be dropping her off to get 4.88s.

I have 3.21 gears in my 6sp and run 33's. It was a bit of a dog, then I put a CAI and Cat Back- it made a difference.

Now I am going to 4.88's with 35's. But the later is fine too..

I have 3.21's and a 6 speed.....it is bearable enough that I won't be changing gears till my last mod. I almost guarentee if it were an auto I would be unhappy. As it is now I just downshift to climb in the mountains. Flat roads and in town it is no problem at all.
