The one item that catches my eye is the galvanized steel pipe that you mentioned. I would suggest that if you can you should replace it asap with copper, or pex, whichever you feel more comfortable working with. Old galvanized pipe is frowned upon by most home insurance companies, you may not be covered against damages should the pipe fail. Also, be aware that non mettalic pipes do not function as an earth ground for your electrical systems, usually not a problem in newer homes, but in older homes, with 2-wire, or knob and tube electrical lines there has always been the temptation to bond to the nearest waterline when installing a GFI .
As for the pipe insulation, there are a lot of good choices, but what really makes the project work is the fit and finish, especially around elbows, clamps and so on.
You want to fasten the insulation to the pipes securely so that it would be difficult to accidently pull off; a lot of good work can unravel very quicky!
