This is as good as it gets.
I've read that you can disinfect plants by soaking in a solution of 1:20 bleach/water. If you do this, just soak them in dechlorinator and water before planting. I just added mine, not thinking of a problem. I suppose quarantine might be a good idea tho..... I also used some plants that were in my 25g already. Your bkg will love any plants, I'm sure. Try stem plants, these are fast growing and give places to lie inside. An amazon sword in the middle might be nice in your tank as well. It makes a nice centrepiece as it gets pretty big, and grows under lower light with no CO2, quite nicely.
