Forget the UV lamp. Coatings you buy in the store do not cure by UV. Anyways, you do not want to mess with UV cure coatings. The good ones are incredibly toxic, the bad ones do not work.

If you spray the parts and keep the car out of the weather for a month, then there really isn't an advantage to baking them. If you want to drive off and take the car to a car wash the next day, then there is great benefit in the heat lamps.

I would spray and be patient myself.
