Interior structural wood pieces - I want them to be perfectly flat

I run the plywood through a table saw and cut a bunch of 3/4" strips so they end up as 3/4" by 3/4" squares.  And one of the best things I discovered is the joy of using a pneumatic brad nailer to assemble a cabinet.  You use the brad nailer to attach the strips to the inside of the side panels.  Then when you place your plywood up against those strips you come in on the inside and brad nail straight into that board.  You end up with no marks on the outside.  I usually use wood glue and the brad nails just hold it in place till the glue sets.  Its easy to space the strips just use another strip or piece of plywood to space them in from the edge and it gives you a perfectly square corner edge when the two pieces of wood are secured to the strip.  Or if you want it inset just add something that thick for the extra spacer when you are attaching the strip.

Thanks again everyone.  I bought four sheets of MDF because I had to rent a Home Depot van to get it home and didn't want to have to rent it again for one more sheet if I needed it.  I cut up one of the four, and I have no need for 3 extra pieces of MDF.  I don't have any room to store it. I will probably use the one I cut up for control panels (I am planning to have interchangeable control panels using hand knobs in the corners to tighten them down).  Now that I have my design more figured out, I may only need two or three sheets of plywood.  I will be sure to figure this out before returning the MDF.  I don't have a brad nailer and don't have a way to air power one, so I will just stick with screws and glue.

Are drywall screws good for maple plywood?  What circular saw blade do you recommend?  I was suggested to get a fine tooth one so it wouldn't screw up the finish, but the one I got dulled so fast, it ended up curving my cut.  I haven't used my router yet, but I have a cutting bit for it.  Wouldn't this work just as well as a circular saw if I ran it along a guide?

Thanks again!

I bought this kit and at the time I wasn't even really thinking I needed the attachments.  Once you use this you won't go back.

Thanks.  Since I don't plan I building more than one cabinet, I will save the money and space in my very full garage and just use screws and glue.  I have a nice powered screwdriver, so hopefully that will get the job done almost as easy. 

After doing some research, I won't use my router to do my cuts.  I will get a Freud D0760X blade for my circular saw.  I also have a jigsaw for the rounded parts.  Hopefully drywall screws will work.
