Are there any special tools required to install this?

The Sloan wrench makes this much easier (you can use an adjustable wrench if it opens big enough) Example of the wrench:https://www.amazon.com/Sloan-Valve-A50-Super-Wrench/dp/B00117CUA4/ref=sr_1_1?keywords=sloan+wrench&qid=1571415130&sr=8-1

How many gallons per flush?

1.3 looks at your bowl by where the pipe goes into it should be imprinted right there

will this repair kit work on Sloan royal flushometer model: 111-1.28 ?

Sorry I don't know for sure. My limited experience is that Sloan are pretty standard internals.
