The Romanian visa does not make much difference, except perhaps in allowing you to lodge your visa application in a consulate in Romania instead of your country of origin. You will still need to fulfil all the requirements of a regular Schengen visa.
Also, being a resident of a rich country like the US or UK would seem to bolster your credibility as a visitor but I am not sure that what is essentially a temporary status in one of the poorest countries in the EU really helps all that much (even if I suspect that nobody would say that officially).
