Here's the deal:
There are places out there that can fix a wheel, just check around at some local body shops to find out who they use and if they are reliable. This usually requires sending the wheel out to them for about 2 weeks and runs anywhere between $110 to $200 depending on the damage.
Best option for the tire is to get a new one and place it on the rear so that the tread is the same on the 2 front tires. Once you drive your VX for awhile it will wear the new tire enough that it won't matter when you rotate your tires 6,000 mile later.
Third option, buy a new set of aftermarket wheels with the tires already mounted (wheel/tire combo) from almost any internet wheel dealer. Cost anywhere between $1500 to $4500 depending upon what you want and how fast you want it.
Good luck!!
Oh yeah, lastly take off the spare on the front and put one of the rear wheels in its place. Drive and see if the noise is still there. If the noise persists remove your brake rotor and check the wheel bearings, the curb impact could've cracked one which would cause a grinding sound.
