Welcome to every hard drive ever.
This is because the hard drive manufacturers say a gigabyte is 1000 megabytes, and 1 megabyte is 1000 kilobytes, rather than 1024 kilobytes.
At the kb level, you lose 2.4% (24/1000). At the mb level, you lose 4.8%. At the gigabyte level, you lose 7.2%. 350 gb * 92.8% = 32.5 gb, minus a few for the operating system. So yes, it is normal.
As for the RPM,
Apple menu -> About This Mac -> Serial-ATA
You'll have to copy/paste your hard dive model # and do a bit of searching, but I'm sure you'll be able to find it.
