I also have an '07 with over 60K miles and still adding miles to it...with your '07 with only 21K miles is considered very low mileage for a touring bike...
Q1 Answer: no, it is not normal to have a whiff of gasoline anywhere around your bike. I have not noticed this on my bike while parked in the garage. As stated by a member, it could be a minor carb issue.
Q2 Answer: the RSV should not really run very hot especially on hot summer days. Perhaps try to replace your coolant and if you can get to it, replace your thermostat. I personally have not replaced my thermostat, so I don't know exactly hot to get to it. I've only replaced my coolant a couple of times already. With all that, hope it helps.
Ride Safe.
