New sprockets and chain

I ran a 16t front with a 47t rear for a Summer. Freeway cruising wasn't much fun (I think I was running 5000 rpm at 70mph) but around town it was a real gas to ride. Reminded me of the time I put 5.13 gears in my Z28 for the street. Nobody ever beat me out of the hole!

  Speaking of spockets, what effect does using the sizes you reccomended have?
  I forgot the way it works going up and down teeth, front and rear. I was thinking of making mine hit harder off the line, one of my friends says I want to turn it into a 'wheelie machine'. Which way would I go with this in regards to front and rear sizes?
  A little off topic- I was thinking of getting a replacement swingarm, having a shop widen it quite a few inches, using a wider wheel, and mounting a 250 to 300 rear tire.
  Any input on how to reliably make the front tooth align with the rear? My best guess is to have a new shaft made. I'm also wonding if having some sort of spacer machined will work.
