Kotor combat system?

[Gunners_rule]

Just had a couple of basic questions about Kotor's combat system:

1. When a damage breakdown is given in the feedback menu, what accounts for the energy value? For eg. Damage breakdown: 8 = energy 6 + weapon specialization 2

2. How is the attack modifier calculated when using double bladed weapons or dual wielding? An example, perhaps?
 

3. Is Critical Strike the only attack that can stun opponents (as opposed to Flurry and Power Attack)?

4. Can someone explain the blaster shot deflection/return mechanics please?

 

Thanks
