Yes, with that kit you're automatically replacing the body mounts, as the extra 1" is built right in. So new poly mounts and an extra inch of height is a great combo. And very good bang-for-the-buck for sure.
For just one inch enthusiast, you don't always have to do anything. I got lucky and didn't on mine, but not everyone is as lucky. For starters, here's a small list with expectations.
During the installation:
1. Always disconnect your fan shroud, if applicable.
2. If an automatic trans, it wouldn't hurt to disconnect the shift linkage. At least take it out of Park. Same for manuals, but it's usually not necessary.
3. Unless taking the body off, just do one side at a time. Loosen all bolts, but only remove the 4 per side as you do the lift. It's just easier with common garage tools this way. If you're a well-equipped shop, you can do all 8 at the same time easier than most of us.
After the install:
1. About 50% will have to lower their fan shroud. The other 50% don't.
2. About 10% with automatics can simply adjust their linkage to compensate. The other 90% will need to lengthen the rod or purchase a new longer "cut to fit" version like this:

3. About 5% or less with manual transmissions can get away with re-adjusting the clutch linkage. The other 95% will need to lengthen the pedal-to-bellcrank rod. You can cut and section your old one, or purchase a longer adjustable one like this:

As a side note, and to push more product, more and more owners are going to find themselves with worn out clutch rods anyway, so buying new is not out of line. It pays to inspect yours first, so you'll know if it's in great shape, or on it's way out. Easy to tell...
4. About 95% will not need to modify their steering shaft or joints at all. However, if your steering setup is already non-stock, or you're in that other 5% of EB owners, you may have to change to a collapsible shaft with 2 joints/yokes, or similar setup. This is what we sell
http://www.wildhorses4x4.com/product/Custom_Lower_Steering_Shaft and you can check out the video to see how easy it really is to install.
5. About 99% won't have to do anything with floor shift levers for t-cases and the like. Every once in awhile it crops up, but only rarely. On 2" and 3" body lifts however, that percentage changes drastically.
6. With only 1" of lift, nobody should really have to mess with their fuel filler hoses or anything like that. However, here again if you're non-stock and something isn't giving you any leeway, that's going to be an individual Bronco kind of thing. No way to predict that kind of stuff.
That's about it. Most tolerances are more than adequate for a 1" body lift. But as you can see by the fact that it's not 100% for most of that, we fall back on the "every bronco is different" saying.
Have fun. The worst part is usually removing the old mounts. Rust again...
Want a percentage? From what I've seen, about 25% of owners can get theirs right off with no drama. Helped a friend with a '73 and we had them all undone and off in less than 10 minutes. Unfortunately, the other 75% of owners fight like the dickens! In those cases, some are lucky to get the job done in a single weekend even!
Good luck.
