What do these codes mean?

Got a bonus from my friendly Dodge dealer, a free diagnostic scan. I got 3
codes which were:

1. Upstream O2 sensor
    ( I've got 65k miles so I assume I'll be changing all of these, right?)

2. Idle air control motor air
    ( I did smooth the top of the TB flush, could this be the cause?)

3. TPS high voltage
  
Any idea's on these? Dak is a 97 5.2 auto 4x4. Mods are: K&N FIPK, milled
flat TB, Gibson headers, Gibson cat-back, 180 t-stat and 3923's. Thanks.

Jake
