Judging from how bright your light look, I assume you're running at max setting/3PM. I'd suggest running at 9AM for the moment until you get more plant mass and the plants are settled in. Also for a tank with that height, 12PM setting is optimal without CO2. 3PM/max might be too much unless you have tons of fast growing plants. Lighting should also be limited to 6-7 hours a day without CO2.
I'm running some Aquaclear 70 on my 55G and the current it produces is really strong. Would put a lot of stress on most fish and even more so if you're planning to put in a powerhead. Might wanna take that into consideration. As a suggestion, for my 20G, I run 2xAquaClear 20, one on each end of the tank at reduced flow. Fish are happy, plants are happy.
For plants suggestion, Rotala indica/rotundafolia and duckweed would do a fine job.
As for surface film issue, the AquaClear filter itself is enough to break the film. In my experience, it will go away, along with the film on your driftwood, once the tank is fully cycled. The more I mess with it, the worse it gets. Daily 10% water change might help.
