if my ISP won't "let go" of the DNS for my IP then can I not put it in my DNS?

This generally isn't a problem.  There's no requirement that there be a PTR
record for every A record.  So it's fine if both names
<something-random>.dsl.pb.net and www.<yourdomain>.com both point to your
IP address, but the PTR reverse lookup only returns
<something-random>.dsl.pb.net.
