Not sure why you would want to do this. You will be losing climbing ability.
You haven't said what the crankset generation is, 9-speed, 10-speed, etc.
It will probably work.
You will need a new bottom bracket in the correct length for a double. It will need to be compatible with your crankset and your frame.
What you will need to adjust are the front derailleur limit screws.
Follow the front derailleur adjustment instructions found at http://www.parktool.com
precisely. Do not leave any steps out.
If you do the work yourself you will need the correct tools.
Is it worth it for a small weight savings?
You will not need a new rear derailleur, the weight savings of a short cage RD are very small.
Is the frame worth spending a lot of money for components? Usually the answer is no.
