I wish to register a new domain with Network Solutions, can I enter 3TEC.COM's name servers information?

Yes. However, you will need to subscribe to our DNS service in order for www.your-domain.com to be resolved to an IP address on the Internet. The name servers you should use are NS1.3TEC.COM (IP address is 65.22.7.10) and NS2.3TEC.COM (IP address 216.40.47.18).
