I have a domain from netfirms, with nameserver on reliable dns. But one subdomain I wonna send to rackspace server.

So what I should do, change "A" of subdomain to IP of rackspace server or add rackspace ns to the list of reliable ns I already have for whole domain?

You want to create an A record for your subdomain and point this to the IP address of your Rackspace Server
