Good luck going planted. Here I go....
Yes, what kind and how much lighting do you have?
The grass looks like Blyxa Japonica..? If you haven't do some research, that could turn out to be a discouraging beginning plant.
edit:After looking some more, not Blyxa. Not too sure. Doesn't look too healthy though.

The lily will start to wither on you. It really is an emersed plant and doesn't do well submersed. Just a warning for when it starts to die.
Ditto for what gmh said.
The hygro is good. I would look in to getting some more. It's a fast growing plant that is very beneficial to the tank. Try trimming the tops of your hygro to promote more growth while your tank settles out.
Moss is always a winner. You said your driftwood started getting slimey. When you get that resolved attach the moss to that wood.
Here's a link for your moss:
