Surround Sound & Logic Audio Advice, Any advice on surround controls Options

[melta]

Can anyone give me some tips/advice on using surround sound on Logic Audio?
I use a G4 laptop (400mhz), Logic, MOTU 828 and Analogue Mixer with direct i/o on each channel (only have a stereo master bus).

Q: Are ther any joystick like midi controllers for panning sounds around 5.1 or 7.1 surround sound, using Logic? which aren't at crazy hollywood studio console prices??
Q: Does LAP6 offer significantly more surround sound control and functionality than LAP4 or 5? (I'm about to upgrade from LAP4.7.3x)?
Q: When I create a Surround sound mix in Logic and route it out the 6-8 outputs of my MOTU828, will I still have to use a Surround Sound Bass management system or will Logic do this?

If anybody can help or give pointers i would so appreciate it (the webs pritty empty on this subject). Thanks
