Any advice, tips on adjusating the tracks on the Cat 60?  Should the bolt through the tension springs have a little clearance at the front or whould it be tight against the idler carrier?

The captured length of the front idler recoil spring is set at 17 1/4" - once set, you do not change that length. The nut that adjusts that length is at the rear on the spring.

Loosen the clamps bolts (also at the rear of the spring) and turn the "front idler adjusting bolt" to tighten the track. The book says that you should be just able to lift the track off the track 2" off the carrier rollers. Both the inner and outer bolts should be kept equal to have the tracks run straight.
The "Tandem Recoil Spring Group" - used on the Logging Cruiser tractors uses different parts and measurements, but the adjustment is the same. 
Hope the attached pictures are a help.

Thank you, I see all that from the manual but my question is should there be any space between the back of the adjusting bolt and the carrier? I'm guessing the "captured length" is the fully compressed spring but how would one know that unless it is completely compressed? My spring measure about 20" and are almost compressed, I don't think they've been changed. I wanted to take the sag out of my tracks and just wondered if there should be a little tension on them (space between the back of the bolt and face of the bearing carrier).

There are 2 separate processes here. The length of the spring (17 1/4") is set when the track frame is assembled. The spring is only compressed further when the tractor encounters an obstruction that forces the front idler back further.
Loosening the the clamp bolts and lengthening the adjusting bolts equally will remove the sag.
In the second picture above you can see about how far from fully compressed the springs on my tractor are.
