I believe this is self-explainatory:
1) Bitcoin usually runs on port 8333. Why?
2) Bitcoin does not show in up http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml .. why?
3) What needs to happen to have someone from the Bitcoin foundation
to fill out the form asking for an assigned port (see
http://www.iana.org/form/ports-services )
4) what should the process be for new cryptocoins to get both default
port numbers, as well as P2P network identifier 'magic numbers'

IANA normally register ports with the principle of conservation in mind.
See section 7.2 of RFC6335 for more details.
http://tools.ietf.org/html/rfc6335#section-7.2
8333 and 18333 are currently unassigned, which is good news.
Ideally it would be good to have two ports, one for the main net, and one
for the test net. However, in light of conservation only one may be
granted. The question as to whether traffic could be multiplexed over a
single port may be raised.

If a whole slew of alt coins also tried to reserve ports, I suspect that
may raise eyebrows.

I have requested an assignment.

I'm sure it would be *possible*, but testnet and mainnet are entirely
separate networks. Not only that, but the entire point of the testnet is
separation. There is no logic to multiplexing them.
If conservation is an issue, I'd forgo the testnet port. We don't have a
'test ssh' or 'test mail server' port either, most people will just
allocate a temporary number for those themselves.
In case the port is already in use, bitcoin can run on and announce any
another port. There is no strict need for it to be 8333 (or 18333) at all.
There isn't even an argument for convenience. Most of the time, users don't
specify nodes. And in the rare cases that they do they can specify a port
as well.

That's somebody else's problem. Bitcoin is by far the most well-known of
the 'coins' so it may be considered realistic to allocate one or two ports
for it. Or not, in which case the altcoins can forget it too.

Wladimir
