Hi bigmike,
Since you're in Zone8, you could put it in ground. If temps are above 0°C/30°F, so no freeze, you could plant it now.
I would plant it right away to avoid the watering problems and possible root rot from too much water.
As to pruning do it in July if really needed. The reason is that some limbs are perhaps already dry, some others will start growing and crumble for whatever the reason.
So let them grow and select the best and thickest in July or August. If, by that time, you see some branches are too shaded from other leaves, then remove them as they will die or crumble.
That happens near the trunk on the shortest limbs and on branches growing back to the center or on lower branches.
For now, don't keep the tree inside the house, or it will awake. Outside in a pot it could freeze solid though. So as said, IMO, the safest is to plant the tree asap - if you've planned to do so.
If you're going potted tree, than time to fetch some good pot and potting soil from the nurseries or whatever suits you best . And don't prune before Summer .
Good luck !
