If I remove the middle ring will I need new, shorter chaingring bolts in order to secure the large outer ring to the crank arms -- or will the exisiting ones work? Or worse, am I screwed all together and can't remove the inner rings at all?

Here's the link to the model of crankset I have:

I would go to the LBS and ask for a set of single-speed (sometimes called "BMX") chain ring bolts. To put the chain in the middle of the cassette, it may be necessary to mount the 44 on the middle position (assuming it clears the chainstay).
