First, call your local building inspector regarding local plumbing codes, permit, and inspections.
Re-plumbing is a major project, and only YOU can determine if you want to tackle it, or call 3 plumbing contractors for bids. Dealing with old galvanized lines and cast iron drain pipes can be a job.
(When I built my house, I had copper lines and pvc/abs drains installed.)
For ease of installation and repair, IF it is permitted in your locale, I would go with pvc for cold water supply, cpvc for hot water supply, and pvc and abs for drain/waste/vent system. (Some places won't allow pvc/cpvc for water supply, however.)
There also are other alternatives, and some of the pros in here (I'm not one) may post another opinion.
Good Luck!

Just a tip.
When you mess with old galvanized you will disturb all manner of gunk that has built up over time. I prefer not to do partial replacement of this stuff, but to get rid of it all at once. Altho' its more invasive, the overall expense is usually less and you avoid having rust etc. come loose over the course of months, giving you poor water quality, clogged strainers, and ripped up faucet washers.

Sometimes it's unavoidable tho' to do a phase at a time. Flush the lines well after doing each phase of the work and clean out the strainers often.
