I am fairly new to TIG welding.
What are the pro's & con's of push versus pull techniques ?

Ideally you want the torch to be straight but pretty much it is whatever is best for you I do about a 15 degree push angle to see the arc and to feed the rod in the puddle of you pull it you can't see thepuddle depending on how you sit and it is harder to add filler. Learn how to do both in case you have to do it the opposite way someday.
A student now but really want to weld everyday. Want to learn everything about everything. Want to become a knower of all and master of none.

The heat from your arc generally travels in the direction you point the torch. So if you need deep penetration then focous on pointing straight down. But if you are trying to tie in to an existing weld sometimes it helps to point the torch toward the edge you want to break down. Also you can use this to your advantage on a thick to thin joint by pointing your angle towards the thicker part. The advantage comes from knowing when to point your heat in a given direction.
I have more questions than answers

Mostly you use a slight push angle.
This gets the puddle out in front far enough to allow the puddle to melt the wire instead of the arc.
Sometimes you may have to pull due to obstructions or to help build a taller bead for a specific purpose.
Also, when welding in a small circle, like the end of a steel pin or plug welding, torch is straight and filler gets added from side, back, front as needed.

Push or straight up and down.
Pulling the torch with a little angle and trying to keep a tight gap between electrode and base metal is a bit tricky if you have to also feed in rod over the raises stack of bead you just laid with out fouling the tungsten, cleaning (if aluminium) and heat probably isn't going where you really want it either. As others mentioned there are times you can dab in a few here and there at odd angles but not for long beads.
