[Psionics] melee with TK Grab + Levitation + Power Defenses + CM1

[aldebaran]

Hi, I am trying to figure out how to correctly use TK Grab + Levitation + Power Defenses + Compartmentalized Mind 1 (CM1) during a melee combat. Please let me know if anything I describe below is incorrect from a RAW perspective.

Here are the assumptions :
- PC has TK Grab, Levitation, CM1, no melee weapons skills at all
- PC is levitating 1 yard above ground (PC succeeded Levitation skill roll 2 rounds ago)
- PC is using TK Grab to wield 2 quarterstaffs in his square thanks to CM1 (PC succeeded 2 TK Grab skill rolls during previous round to grab the staffs)

On his turn, PC is allowed to do ALL the following :
1- Use 2 mental maneuvers to continue using the staffs with TK Grab; 2 TK Grab skill rolls are required to maintain the grasp on the staffs
2- Strike a single attack with each staff at 1,2 reach by rolling again vs IQ based TK Grab skill
3- Maintain Levitation as a free action
4- Move 1 yard in any direction while levitating

When defending during the same round, the PC can do ALL the following :
5- Retreat 1 Yard while levitating
6- Parry against 2 attacks using the staffs at (IQ based TK Grab skill/2+3 +2 for staff +1 for retreat vs foe from which PC is retreating)
7- Use Power Defense twice at (TK Grab skill/2+3) to reduce any incoming physical damage (as per Psionics Powers p8 rules) of any not parried attack (possibly the same attacks that the staffs attempted to parry)

If PC is injured, he has to roll vs Will-3 twice to avoid losing grasp on the staffs.

Your help and advices will be very much appreciated !
