what is the difference between top normal and low normal?

Top normal is most common. Derailers are defined by the normal position of the derailer (that is the resting position), either the top gear or the lowest gear. The way to check a derailer is to release the shifter cable and see where the derailer moves to. The top gear is the small side fo the cassette and the low gear is the larger side of the cassette.

will it work with brifters on an eight speed

Simple answer: yes.

It's a loaded question though. While this derailleur will work just fine on an 8 speed setup, an 8 speed chain is slightly wider than a 9 speed chain, which can grind the cage pulleys down if you do nasty things like cross-chaining.

Beyond that, most 8 speed systems aren't worth upgrading to something this fancy-schmancy. If you're wanting to move on up in the componentry world, be sure to grab all of these things too:

If you're not down with all of that, seriously, convert to SRAM X-9. It's better, lighter, and cheaper.
