1) Do I tighten the bow to playing tension when I rosin it?

Yes you must tighten the bow when rosining it.

 

2) Do I put a decent amount of pressure on the bow when I rosin it? The bow and rosin are brand new and I know that I have to break through that glossy layer of Cecilios rosin but I didn't know if I needed a lot of pressure to do that...

 

Yes, use a decent amount of pressure till you start to feel friction as you are rosining the bow.  All of this is only the first time you rosin a newly rehaired bow. Later you will only need to apply a few strokes every once in a while.

 

3) After 15-20 minutes or rosining I took the bow to the violin and on the middle part of the bow was catching the strings and not the top or bottom of the bow near the frog, despite my complete strokes of rosin from top to bottom. So is it OK if I just rosin certain parts of the bow at that point, or do I keep doing complete strokes...? 

 

Very much OK to rosin those sections of the bow that are not grabbing the strings.
