When seating short for cailiber bullets ie .30 cal.  Is it better to be concerned with the distance to the lands, at the expense of the bullet being .30 deep in the case neck, or vice versa?

All you need is enough bullet seated in the case to keep it from coming out. However it's rarely possible to seat a lite for caliber bullet close to the rifling.

I normally go with the bullet makers reloading manual recommendation.

If you don't have the manual, name the cartridge and bullet, we can look it up.

Rule of thumb is one caliber length inside neck for proper neck tension.

In your case .308  of the bullet length should be inside the neck.

.308 Win., 135 gr. Sierra Matchking, due to the boat tail, only about .175 of bullet bearing surface is being gripped by the case neck, if I add the boattail then I've got about .325 in the case.  What do you guys think?

That should be ok for a bolt action or semi auto if fired single shot.  Bullets can move under recoil in the magazine so I wouldn't recomend loading more than one at a time.

The boat tail doesn't matter, only the bearing surface.  It's less than the rule of thumb, but you should try it and see if it works better or worse.  I don't think I'd load from the magazine, though.
