Hi Ric,
The pear tree should be planted so that the 'nursery mark' a swelling just above the roots, is above the surface of the soil, this way, it will prevent the root-stock from sending up suckers and weakening the growth, this may also be known as the graft point/mark.
Staking to give, good support is always wise. You can angle the stake at 45 degrees to avoid damaging the roots but be sure not to put the stake on the windy side, otherwise it is likely to be pulled out of the ground when the wind catches the crown of the tree, also make sure it has a tie/spacer to prevent bark rubbing on the stake.
Pears flower a bit earlier than apples, so can suffer frost damage, if the position is sheltered, it will probably be ok. Otherwise it can be protected over the winter by an 'horticultural fleece'.
If there are other pear tree nearby they may act as pollinators and improve your yield.
Happy Birthday btw - Chip
