Hi, I think this should be a relatively easy job to do, But plumbing is like wood working, nothing fits as is. You may have to do some cutting. Plastic drain pipes are easy to cut to fit. Check out my Blog and see what I had to do just to replace my bathroom faucet. "Simple Safari faucet change?"
Bigger problem is redoing the counter and formica around the sink. On my Tradewind I kept the sink but had the faucet replaced with a new unit and then put in new formica. The whole counter assembly came apart with a phillips head screwdriver.
