Since you're not using ZZ, don't worry about only solving F2L with RUL, F moves are fine. About PLL, there was at least one solve in the average where you used 2-look, so you might need to work on your recognition a bit.
If you are still learning more COLL sets, I would say you should decide whether you want to know a lot of algs or get fast faster. If you want to have knowledge of a lot of algs sets, then that's cool, go ahead and learn COLL. But if you are just trying to get faster solves, trying to focus on COLL at this stage is just wasting time that you could be using practicing. Save that for more like ~15 seconds (and honestly I would go for full OLL before COLL).
And just to make sure you are aware, the second solve would be a DNF because of the slice move.
Hope this helps
