Planting density & driftwood, lighting (Newbie)

Hi
Just a couple newbie questrions. Setting up my first planted tank, will be
a low-light tank and low maintainance. Will be planting Java Fern,
hopefully more than one variety just depends what my LFS can bring in,
Anubias barteri var. nana, and Crypt walkeri or wendtii and maybe Java Moss.
I was thinking 6 Java fern, 4 Anubias, 1 or 2 Crypt and 1 or 2 Java Moss.
Is this a good density for a 33 gallon(36"lx12"w) tank or should I put
more/less in? Are these plants a good choice or should I see if I can find
something else?
Also I would like to put the Java fern/moss on driftwood, but I'm having
trouble finding aquarium friendly real driftwood that I like, would the
resin driftwood work or is there a reason you would use the real stuff?
And finally, is there a website or someone who could explain the difference
in bulbs/lighting numbers in laymans terms. (I'm just wondering about normal
fluorescent bulbs). I was looking at big al's online and there is a lot to
pick from and I have no idea what the difference is between a lot of these
bulbs.
Thanks for the help
