I'm a tad confused whether you want to use the MBP with the lid closed or make it go to sleep.
Read through this Apple TIL and see if it helps:

Putting it to sleep from the "drop down" works, however it will not wake up from the Mouse nor the Bluetooth, once again the lid has to be raised.
I have not yet been able to operate with the lid down.

The Mac Gremlins are at work. Here it is one month to the day of my original post and just like magic, today it works as advertised. I can now work with the lid down.
The only thing different is I did upgrade to 10.7.2 earlier in the week BUT it did not work at that time or anytime thereafter when I tried it. Until 15 minutes ago
I normally put it to sleep then close the lid as a normal "done for a while" when leaving the desk. NOW when I close the lid (without putting it to sleep) it works just lovely.
Putting it to sleep works but has to be awakened either with a USB connection or raising the lid.
