Yes, if you plan to do your own maintenance and remove wheels, definitely get a stand. I managed to remove the front wheel without one on an SV, however it's a pain in the bum as you need to lift the bike onto some sort of a support and then you worry about it falling off. Keep in mind that many front stands will not work directly with your bike. Some come with adapters but even those may not fit. Double check before you buy.
Flat spots, however, don't worry about those. You would need to store the bike for a prolonged period of time, not just one winter. Plus you can always move it a bit.
Centre stands are an amazing thing, btw. So glad to have one on my current bike. In the name of weight reduction and cost saving very few bikes, even the ones that claim to be touring, have one. On the VFR I never use a rear or front stands to remove the wheels, just weigh down the front or rear while it's sitting on a centre stand.
