Well I've decided to finish my attic. This will be my first project of this magnitude, so it will definitely be a learning experience. I've done a good amount of research, so I have an idea of what I'm getting myself in to. I need to put in a floor on the sides, behind where the knee wall will be. My attic has an old tongue and groove floor in the middle, but will this work as my sub floor there? Hopefully I don't have to tear all of this up.
Also, I'm not sure if I should frame the knee walls first, or if I should insulate the rafters. It would obviously be easier to insulate behind where the knee walls will be if I do it before I frame them, but I have heard not to insulate until you are ready to drywall. Plus I want to either have track lighting or recessed lighting in the middle of the ceiling, where there will be a small flat section, so I would think I would want to wire that before insulating.
And about the spacers to keep the insulation from contacting the roof... how far apart can these be (vertically)? Do they have to be right on top of each other or can I spread them out? There are vents in the roof, will these be alright or will they cause problems? The plan is to have the rafter spacer things, and then have a section of flat ceiling where I will put lights, and I will have open air above that for ventilation. This way air will be able to circulate between all the rafters and the vents on the end of my attic. Good plan?
How high should my knee walls be? I think 4 feet would be convenient, since I wouldn't have to cut the drywall, not that that is very hard, but less mudding too. I am planning on just nailing the studs to the side of the rafters, instead of using a top plate and having to bevel it.
Here's some pictures of what I'm working with. Any input is welcome. Thanks!

Need to put a floor here for storage behind the knee walls.
Not really sure where to insulate here.
Need a floor here as well.
Vents in the roof. OK? Also, old knob and tube that will be coming out.
Vents on the end of the attic and more knob and tube.
