Mild leveling questions

I have an '06 Tacoma and want to do a really mild leveling job. I'm actually pretty happy with where the rear is right now, and just want to bring the nose up a bit, close to level with the rear. I was thinking bilstein 5100's with stock springs, but I don't know for sure that this will work? If so, what setting on the billy's will be about right?

Assuming that this is something that is do-able, and isn't a horrible idea for one reason or another, what would be a good tire size that will work without too much rubbing? Stock 17's will be used, so something like 265/70's or 265/75's?

Thanks in advance for the help guys
