1. Everything you sent looks good.  I would not worry much about the rms.
2. The scalar vs vector is a good test.  L band phases tend to be stable as you found.
3. Everyone uses 2pt  stay with it for L band.
4. The gain calibrator is a good phase calibrator (or it would not be a good gain calibrator) 
5. The rms is just a measure of the deviation from the mean
6. The calibrator image looks correct.  Your source has a 2nd source within the beam.  The amplitudes and phases will reflect both your source's structure and that of the 2nd source.  So amplitudes and phases will be a function of the location in the uv plane (calibration sources should not have this problem).  Go ahead and make an image - but image a large area so as to get both sources.  The LIST option actually looks pretty good.
You are worrying too much - things look good.
