hello, i recommend to install it, configre and test as normally for a normal virtuemart checkout and then enable OPC. Paypal pro is not a part of standard virtuemart distribution and therefore you might need to purchase it somewhere.
there should not be any issues with paypal pro as OPC does not alter any of the functionality involved, but in case you encounter any issues, let me know.
best regards,
stan
