Have a client registered with Network Solutions and been trying for a week to change the nameservers. Needless to say it's been a nightmare...

If I transfered the domain to OpenSRS would they lose the time alrady paid for?

IE: with NS, domain is good till 2003, transfering to like 000domains, would that tack on another year to it or would they lose those 2 years?

Nope.. It'll add on a year.. =)
