The tree is presently planted in heavy clay soil and is approx. 4 ft. tall. I wish to relocate it to a sandy loam area. This area has a hardpan layer approx. 24-30 in deep, otherwise good drainage. Do I need to break through the hardpan layer? What else do I need to be concerned with?
I would break up the hardpan area and amend the soil with compost prior to any transplanting. Also, you should keep in mind that sago palms do not like to be disturbed, so any transplanting needs to be done with great care. Mature palms can be transplanted in early spring or late fall. Include as much of the root system as possible when digging up and moving it. You may also want to consider trimming the plant back to prevent transplant shock.

I am located in the South where we don't normally receive snow. This year we actually received approximately 5 inches, destroying my Sago Palm. The palms are approximately 5 feet tall but are completely yellow in color. When I look out my window, it looks like a school bus. A local horticulturist stated that the fronds should be cut off completely. Is this true?
I would wait until spring to cut back the plant. It will help protect the new growth, just in case another freeze occurs. But, you will need to remove only the yellow and brown fronds in the spring. Do not remove green fronds. These articles will help you as well:

Down south in Alabama we had a hard winter. Most all the sago plants took a beating and most all are brown from top to bottom. What should I do?

Due to the extreme cold winter here in Houston, many of my sago palms have turned brown. Should I trim the dead fronds off in hopes the plant is still alive, and will come back?

It is hard to say how well they will grow back. Sago palms do not deal well with lost fronds, but they have been known to recover fine. I would wait a whole season to see if fronds grow back.
I live in LA and my sagos went through a freeze. Is there any help for them? Should I prune and hope new ones will grow?

My sago palm has no new growth on one of it's stalks. Is that stalk dead or will it possibly come back?
It can come back if the stem is still alive. This article will help you determine if your sago is still alive:

A sago palm was subjected to freezing weather, below 20 degrees. All of the foliage has turned yellow. Should I trim all of the yellow stalks off and leave only the trunk?
Wait until spring to do anything, in case another freeze occurs. Then go ahead and trim off all the yellow and/or brown fronds only. Do not cut anything that may be green.
