A punch list of problems on my truck...

[Derrickbwg]

I just recently got the truck and it has numerous things wrong with it that I am trying to correct. Here is a list of my problems now that I would welcome any suggestions on what's wrong and how to fix:
When I put the truck in gear it wants to creep forward unless you really stand on the brakes, then the brake pedal gets softer and softer and ultimately ends on the floor(takes about 45 seconds) and then the "brake" lamp in the dash comes on. Let off of the pedal and press again and it's back to normal and the light goes out but will consistently repeat the same procedure. Bad master cylinder?
The dash light on the far right will not work, is there an fix to a bad printed circuit because everything else works great? Any way to check to make sure that is the problem?
The blower fan works on the first two settings but the third "high" setting actually goes slower. Is that a bad blower motor pulling to much or the switch?
I'd appreciate any advice...Thanks!
