USUALLY it includes the mentioned sleeves AND pistons and rings, plus main and rod bearings(yes, they CAN be changed with the crank in place). Plus the head(s) are usually gone through as long as they are off. This includes checking out the fuel injectors if necessary.
So all in all, an inframe can be fairly comprehensive. Usually the only time an out-of-frame is done is if there is block damage or very severe wear, where EVERYTHING should be thoroughly disassembled and checked out.
I hope this helped you!
