At this point it is best to switch learn vocabulary frequency lists. These can be found at the ankisys.net site.
I recommend with making sure that you all of the words that occur more than 100 times in the New Testament. Although this covers about 80% of the words that you will see on any page of New Testament, you will still be heavily dependent on lexical aids and reading will feel difficult. The next level is knowing all of the words that occur more than 30 times in the New Testament. This should be the primary target for a NT Greek reader. After that, I recommend learn vocabulary though root meaning.
