55 gal medium planted tank help

[Micco28]

I am looking to setup a 55 gal, medium planted tank and I have a few questions:

Is this an O.K. stock list? (I really would like to do the puffers so I am open to alternatives on the others)
2 Freshwater Dwarf Puffers
6 Odessa Barbs
6 Snakeskin Barbs
2 Rainbow Sharks
6 Eastern Rainbowfish
2 Rio-Negro Plecos (L 135) {Do I need 2?}

Will a HBO filter, submesible heater, and power head work?

I know i need some drift wood, but I need plant suggestions.

Thanks!
