When I did this for the first time my long term fuel trim was +12% and the stft was around +5%.. So to zero out my trims am I supposed to increase fuel on that specific rmp point until the STFT reads -12%?.. or 0?.. or what?

You'll want to add or remove fuel with the SAFC until the sum of the STFT and LTFT are as close to zero as you can get. Anything from -5% to +5% is fine.

Correct. Only because you'll probably never be in closed loop above 4k, so using your 4k point for everything else will be fine.
