I have a 2007 Nissan
I have a couple of thoughts apart from how strange it is Nissan only wants to repair cars that are under warranty. It is a wonder they have any customers at all.
It is normal for there to be a momentary change in engine note/speed when pressing the brake pedal but the change should not be sustained for two reasons.
Firstly pressing the brake allows a small amount of air into the engine intake via the brake booster but if it continues it could mean the booster has an air leak.
Secondly the engine management system is programmed to maintain a certain idle speed regardless of temperature or what load is applied by the alternator, power steering or air con. Perhaps there is a fault with the idle air system.
It isn't unusual for cars of a certain age to be reluctant to start sometimes but mostly opening the throttle part way before switching on and cranking the engine seems to overcome the problem.

Turning the heat on makes lot of noise
If the blower motor is noisy, the bearing may be getting bad inside the blower. This will require replacement of the blower motor unit. In some cases, foreign objects can fall into the motor casing assembly also making a noise. The motor will need to be removed for inspection
