Alignment Questions

I will start with the truck as some modifications are relevant to my question.

06 Tacoma DC, 6" lift, 35" tires, Camburg UCA....and that's all that's relevant, so I proceed. I just recently installed the camburg UCA's and did my inner and outer tie-rod ends. Then I took it to Curtis Tire to get aligned.
Everything went well and specs are as followed:

Front: Left Front: Right
Actual Specified Range Actual Specified Range
0.3 -0.2 1.3 Camber -0.2 -0.2 1.3
3.1* 1.3 2.8 Caster 3.1* 1.3 2.8
0in -1/16in 3/64in Toe 0in -1/64in 3/64in
9.0* 11.2 12.7 SAI 9.9* 11.2 12.7
9.4* 11.0 14.0 I.A. 9.7* 11.0 14.0

I read somewhere that for 35" tires, 4 degrees of caster is ideal. Does this sound right? Also, is the SAI affected by caster? Or even the I.A?

Thanks, Matt

P.S. Sorry about the hard to read Specs, I don't know how to turn off the word wrap.
