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

No.  Granitcanyon is claiming to be authoritive for the forward
lookup zone.  The in-addr.arpa zone still belongs to PacBell.  There
is really no problem here I can see.

AFAIK, as long as the reverse lookup returns a legitimate name you
should be OK.  There have been some "secure" version of telnetd that
compare names but I don't know if anybody uses them any more.

-Things like MX should work since that info will come out of my own
-DNS, right?

Right.

-I also heard there were some "pseudo" DNS type services out there.
-While that is the *last* resort - I really want to get real DNS
-working as much for the experience as for keeping it simple - I would
-still appreciate pointers to more info about this as I failed to track
-down any such info.

-For now its the raw IP road so I am hoping someone can help
