If an employee becomes a participant on 1/1/08 and fees are paid by plan (therefore, from each participant - including the new participants) on 1/15/08 for charges incurred the last quarter, 2007, is this permissible?

Pooled or individual investment accounts?

Does the participant have an account balance after two weeks? Our DC plans charge participants monthly fee, so if your first contribution to the plan is made on last day business day of the month you will incur the fee. This is allowable. I don't know if there is difference between monthly vs quarterly in being allowed. But is does make the case for charging fees monthly.
