Sandblasting out rust...
Im going to start blasting my truck soon and i have a couple questions. Once im done sandblasting do i need to sand the area before i add filler (if needed) or prime the area?

Make sur when you are sandblasting you don't go over 60psi and keep the nozzle at a 45* to the panel being blasted, otherwise you risk warping the panel

How do I know if i need to put filler on the blasted spot. Besides obvious pitting or holes. I have alot of surface rust that is really light in some places.

I'd use some rust-mor and the areas that may have had rust after you're done blasting incase you don't get it 100%. Any auto paint shop should have it or a similar product.

If it is pitted ,it will need something to fill the pits, if filler prime will not fill em then you will need to use a filler of some varity

if you have a lot of rust pits you might wanna try several thick coats of a filler/primer. it will really cut down on the amount of filler you need to apply. You will need to long board sand the truck... I'd get a jitterbug.
