If I could get a 29gal. tank could I use the following bulbs?:

Coralife 30W 50/50
Coralife 30W Actinic 03 Blue

Yes, but non-actinic bulbs would be better. Daylight, or 6700K (or
thereabouts) are generally considered better for freshwater planted tanks. The
50/50 and actinic bulbs are meant for sal****er reef tanks.

Anyone using Metal Halides in FW?

Some people do, but they would probably be too much for a 29 gallon tank.
