If you have some nitrate readings but no ammonia and nitrites, then you are done cycling. You can add more fishes but slowly - i.e. don't go and add 10 fishes at once. That will cause another mini cycling.
Also, if you are interested in plants, it might be a good idea to read around a bit - some plants don't do well if you don't have enough lights, CO2 and fertilizers. I am guessing that you want some easy plants?
