I've been growing some Oak trees in pots for about 3 years now. They
are doing rather well, but the time has come (I believe) for me to
transplant them to a more permanent home. I'm not the greatest
gardener in the world, so I don't have a great deal of experience in
this matter. I don't want them to die due to my mishandling, as it
has taken some effort to get them to the stage they are at presently.

Is this the right time of year?

Plant them in the early fall, while the soil is still somewhat warm
but the air is cool. This will encourage new root growth without
prompting foliage growth. If you plant now, you might get more
foliage than the roots can supply with moisture.

Is there anything I should know before proceeding?

If the acorns were from trees growing naturally in your area, just
plant them. If they are non-native oaks, you might have to do some
special soil preparation.

Does anyone have any experience in this area?

See my http://www.rossde.com/garden/garden_oak_acorn.html

Are they old enough / too old?

If you have a problem with rabbits or deer in your area, they are
not old enough. Wait until they are saplings with trunks about an
inch in diameter. Otherwise, you can plant them this year.

Any ideas would be gratefully received.
