Just proceed in the SR order, then rince and repeat until all CA have been spent. It's not really complicated, and furthermore it's pretty important to track who moves before who.
What caused me some pause on my first read was when you use a CA for a parry or evade, do you lose your NEXT CA, or just a CA from the total? That would make a big difference, but I now assume you just reduce one CA, from the total number available, and stop acting when you run out. The rest takes care of itself.
How you interpret combat styles is up to you, some people use them very broadly (legionnaire combat style which covers many weapons), and some very narrowly (broadsword). You might even separate parrying and actual weapons skill. I am kinda in the middle in this. As you said, it makes sense to take sword&dagger over simple sword or dagger. In our campaign pistol&sword is pretty popular.
About giving bonuses, I wouldn't give a bonus if you use the combat style as per description, but I would give a penalty if you start using it in the 'wrong' manner. So if you use just a sword with 'sword&shield', or sword and shield with 'sword' combat style, I'd give a penalty.
