Lighting, plants and pH

I have a well established 10 gal. FW tank.  Several  months ago, I
decided I'd replace the plastic flora with live plants.

I have an anubias which seems to be ok - it's not growing, but it's not
dying either.  I also bought a red stem plant (whose name I'll have to
go look up - and I forgot to bring the book) which has grown enough for
me to make cuttings and replant.  

What seems to be thriving are the 3 banana plants (and some Java moss
_covering_ a tall driftwood creation).  Two of the 3 bananas have sent
stems all the way to the water surface.  The leaves on these two plants
are bright, waxy green.  The third plant has grown huge red/brown/green
blotchy leaves.  The roots from these plants have covered the bottom of
the tank (under the substrate).

Other tank inhabitants are 6 glo-lite tetras, 4 cardinal tetras, 2 dwarf
Australian rainbows, an albino cory, a dwarf spotted pleco, and a kuli
loach.  All of the fish have been there for at least year, and really
seem to like the live plants much more than the plastic.

Couple of questions here - 

1)  I like to keep the tank pH around 6.5 for the tetras, but since I
added the plants, I'm having a hard time maintaining this level.  It
keeps dropping to 5 and under (off my color chart).  Nothing has seemed
to be affected by this; I bring it back up over a couple of days and
some partial water changes and pH Up.  Should I be concerned?

2)  The tank lighting is a single 15w Gro-Lite fluorescent.  Do I need
more?  Is there a better bulb?

3)  Should I trim the floating leaves/stems from the banana plants?

4)  I have been using TWP water, and then adding the pH corrector and
the trace elements.  I have also been adding Kent plant nutrients, and
extra iron.  OK?  Not?  Other recommendations?
