Adjust your Energy Saver preferences so that the DISPLAY goes to sleep but not the computer.

Should I keep the lid of the laptop open so the keyboard doesn't heat up?
Yes.

Also (beginner question) what is the difference in what the Mac can do when it is in sleep mode versus fully off?
On the VERY latest MacBook Pros and recent Air models, Apple has introduced a feature called Power Nap that allows them to do some routine chores while sleeping:

Mountain Lion: About Power Nap

Apple - OS X Mountain Lion

But excluding those models, what the Mac can "do" in sleep versus fully off is simply get back up and running a great deal faster (as in "instantly"). There is no practical difference in the amount of energy saved between sleep and "fully off" (the latter of which still draws a trickle charge anyway), so there is no real reason not to sleep the machine for routine use. Apple's own recommendations say to sleep the machine for normal periods of inactivity, only turning it off for transport or for prolonged periods of inactivity (they don't specify what they mean by "prolonged" but my interpretation is "longer than a weekend").

If you live in an area plagued by lots and lots of lightning strikes or power irregularities, I'd add that it is of course prudent to unplug your Mac from the main power source during such periods, or invest in a good Uninterruptible Power Supply (UPS) or both.
