From your list, the CAPM is the most appropriate at this point if you're looking for something 'now'. This is assuming the firm you're with does not use the PRINCE2 methodology.
From your list:
PMP - requires 3 years experience prior to submitting the application
ITIL - not really pm focused, more 'service' as I understand it
PRINCE2 - specific methodology, although you can self-study for the Foundation test
MSP - Managing Successful Programmes - program management, which is different than project management
MoR - Management of Risk - Focused on Risk Management specifically
P3O - again, program or portfolio management focused, not projects.
MoV - never heard of it [Edit] - just ran across this - Management of Value - focused on realization/capture of value on an organization-wide basis as opposed to project management specific.
CAPM - entry-level prior to the PMP, doesn't require as much experience
I'll add one more option - look at the IPMA Level D exam. Similar to the CAPM, but in my opinion a more difficult exam.
