2" is fine. The vacuum the gravel simply stick your gravel vac into the gravel.

my 70 gallon has over 100 pounds of gravel in it, so yes, you are fine. My gravel is only 1.5 inches high due to the fineness of the gravel (GEO), but all is well.
Siphon is very easy as stated above.
Make sure not to suck up the gravel into your siphon fully or it will get clogged. I (and I am sure everyone on MFK) suggest usig the gravel vac on your gravel since wastes will build up there.

Two inches deep is fine for gravel. I never go by weight on substrate. Using coverage/depth as a guide works better IMO.

Alright, so it means i had to buy a new gravel vacummer as i lost the front gravel vacummer.
Cos , i never evacuate the gravel .
