No, the TPSs don't care if the tires are run-flats or not.
Depends, how old are your current TPSs? They last 7-10 years so if you are getting close to that, then yes, replace them.

on both counts. The TPS will work with non-runflats and replacing the sensors is not a bad idea if they are the originals or more than say 8 years old.
Curious... They are sensors, and not mission critical sensors... Why replace them before they fail? I come from a day when there wasn't anything to tell me that air pressure was low except visual inspection and a pressure gauge. I walk around my car at least once a day as a general measure. A visual inspection will tell you if a tire is low when a sensor is bad (and replaced when convenient).
When you spend all of the money for new tires you might as well because you will probably end up having to have your new tires unmounted and rebalanced when they fail.
So why not do it right the first time.
The TPMS were mandated. Plus with run-flats it is a little hard to tell if your tire is low on air.
