What is Hard-drive rpm and what woud benefit from getting a faster rpm rather than more Gigabytes?

The faster the drive spins, the faster data can be read and written. The downside is more heat is usually generated and more power may be used, possibly shortening battery life.

So i'm guessing this just affects installation speed?

No. Anytime the computer needs to read or write data on the hard drive, the operation will be faster because the drive can spin to the correct location faster. With a modern operating system, this happens all the time to support the OS as well as when starting apps and saving files.

Installation and general disk usage. Whenever you save things, like a lot of people do very large image and video manipulation, they would benefit from a faster hard drive since that is where everything is stored and saved!

Notebook drives don't make much heat no matter what the speed, and the power consumption difference is trivial. The only real reason to go with a slower disk is cost.

I also wonder -- is the faster hard drive more prone to mechanical damage?

Nope... for Hitachi drives:
5400RPM Operating - Shock (half sine wave) 300 G / 2ms, 160G / 1ms
5400RPM Non-operating - Shock (half sine wave) 1000 G / 1 ms
7200RPM Operating - Shock (half sine wave) 300 G / 2ms, 160G / 1ms
7200RPM Non-operating - Shock (half sine wave) 1000 G / 1 ms
