Table tennis help

Recently I've picked up table tennis again and would like some general advice on the sport.
I'm more intermediate than beginner, having played on and off for the best part of 5 years, and wouldn't consider myself bad, but wouldn't consider myself good.
In terms of style, I'm very attacking, with a tennis-like shot on my backhand and a fairly aggressive forehand. Another point to make is that I'm a backhanded player.
I don't know if this makes a difference but I'm 14 and 6 foot 2.

My goals:
- Perfect the 4 basic shots (forehand and backhand push and drive).
- Learn the chop.
- Add some dangerous serves to my repertoire.
- Learn the snake shot.
- Begin learning how to do a switch shot, more to perplex the opponent than anything else.

Please comment your thoughts on what is worth working on first, how I should improve, and any other obscure shots that work well.

Thank you! :smile:
