watchin' the gears grind... things I need to know for Rehab

I really, really need to know how to say the following phrases in... let's see... Vietnamese, Cantonese, and Tagalog:

Hello!
Goodbye!
Good job!
Very nice to meet you!

Don't let me push/don't let me pull
Do it like this/Don't do it like this

Sit up, please.
Do as much as you can by yourself. 
Stand up, please.
Push from the bed when you get up.
Back up until you feel the chair/bed with your knees.

Do you need to rest?
Do you want to go to the toilet?

(once on the toilet) If you fall, they blame ME. Don't get up by yourself! Ring the bell and let me help you. (I need to pair these phrases with a significant look and a general air of being a petty martinet with a gait belt. Sigh...)

Bend your knees and scoot yourself up in the bed, please
Roll to the right/Roll to the left
