I am about to undertake some remodeling on my master bath and let me explain the setup first. From my master bad to the sink area of the bathroom there is a half wall with 2 supports because it is a load bearing wall. I want to tear this out and put a pocket door in and make the wall a full one. Separating the sink from the toilet/shower is a door and full wall (non-load bearing) that I want to tear out. What I am wondering is, what do I have to do special because it is a load bearing wall, and since the pocket door will be most of the framing is it even possible to use it in a LB wall?

You have to put in a header above the total length of the pocket door system to carry the above weight. So if you are installing a 3' door the pocket door system will be 6' long. You need a header to span over this whole 6' "opening".

What do you have above that this wall is load bearing? Is it another floor or ceiling w/ attic above?
This will determine what type of header you need to carry the weight above the door opening.

It is kind of weird to describe, it is the side wall for my bedroom, there is no attic above because it is a 18 ft ceiling that goes straight to the roof. Right now it is kind of a rectangular archway and I plan on making it a doorframe. I plan on putting in a 24 in. door so I need 48", I have 55.5 so I should be good there.
