need help with some LUA-Texts

[Aur0r4]

Hello guys, for my Yulu UI Classic I need some help creating some LUA texts, because I can't do it myself.

The following is needed for PitBull Unit Frames:

1.)
HP in percent - with a colored gradient - 100% green - 50% yellow - 1% red (hide text when >99% cur HP)

2.)
Current HP | Maximum HP
Cur HP -> Green | Max HP -> dark green
| = white

3.)
Current mana/rage/energy | Maximum mana/rage/energy
| = white

Can someone with LUA experience help me create these three scripts?

Thank you very much.
