More Manuever questions, still unclear about a few things. Options

Ok, so these manuvers in Arsenal. I admit im still sorta trying to figure them out and need a bit more clearing up. There's been a couple threads already on some but they didn't answer all my questions.

Ok, so first: Tae Kwan Do(and if i recall a couple others) have a Martial Arts ability that grants +1 when fighting against multiple opponents.

There is the 'Friends in the Melee' bonus. Say a character with this ability is fighting against two people. I guess BOTH sides get the bonus, then? My guy's two opponents would get +1 for having a friend in the melee, but since he has that ability, he'd also get +1 to his attacks? And im guessing that this bonus would be applied BEFORE a dice pool split(if he wanted to take more than one attack.)

Finishing Move. I recall this being discussed before. According to the book is says the character hits, they can use up a second attack to take the attack right there to finish off the opponent. By the sound of this, you NEED to have two initative passes minimum to even bother taking this attack. Is this the case? Or is there something more here that im not seeing? I know that to 'activate' this combo you need to have a successful first attack, but im kinda unclear about the initative pass part. Now, someone without this ability, if they wanted to split their dice pool, could attack an opponent twice in a row in one pass. But im assuming you get your full DP for both of these attacks too.

Riposte. This has been discussed before too. If you successfully block or parry, you can take a counterattack. Does this require a second pass available? Or if you are lucky and parry 3 people in a row, can you Riposte each one of them? This sounds like a really nasty manuver if you have the skill and Reaction to back it up. Also, if i'm on Full Defense(Reaction + my Gymnastics Dodge + my Unarmed skill)...can Riposte still 'trigger' or is it on Normal Defense only? Im GUESSING it's the latter but im not sure.

Watchful Guard. Ok, so i don't take penalties until a 3rd attack comes my way, im assuming in that same phase. So someone pops me with 2 bullets i just roll Reaction as normal in an attempt to dodge(if im not on full defense), and then Body/Armor as appropriate, but i take no minuses to these, it looks like. A 3rd person decides to shoot and i guess THEN the negative modifers come in.

Set Up: Ok, Im unsure when the net hits to setup run out, if they do. Again, do i need to have 2 initative passes for this? (Fake the first attack and when attack 2 comes let em have it). For the Set Up attack, is it resolved normally (I attack, they roll their defense, but since it's a fake, not Body or Armor?), then the net hits from THAT get added onto my next attack?

Im still trying to totally wrap my head around exactly how these things work. Honestly, we havn't had a hell of a lot of combat so far in SR4, and we havn't used Arsenal live yet.
