As to the heat:
How fast is the temperature gauge coming up, and how high up does it go? Until the temp guage gets to the bottom of the green, you're not going to get much heat in the cabin. In normal operation, the temperature gauge will get up to around the middle of the gauge in about 5 minutes of driving. If the gauge is taking a very long time to get up to the middle, you might have a stuck thermostat. If the thermostat is over three years old, have it replaced - thermostats are moving parts and wear out. If it sticks open, you won't get much heat. ALWAYS get a Saab thermostat - it's a different design than most aftermarket thermostats, and the few extra bucks is well worth having to do it twice. While in there, the mechanic must bleed the cooling system, which will also help with the heat.
I recommend that you keep the fan speeds low until you see the needle move into the bottom of the green. Otherwise you're just pushing lots of cold air around at speed, making you feel colder.
An "induction service" is a method for removing carbon buildup and other deposits from the cylinders and fuel injection system. It's used if the engine is showing poor performance and fuel mileage, stalling while idling, and excessive pinging. HOWEVER, there are a lot of reasons why and engine would be showing those problems, carbon buildup being only one. If the car is running fine, leave the engine be. If the car shows hesitation, poor idling, etc., make sure that all the common issues are addressed first - the proper spark plugs gapped to the proper setting; NO AIR LEAKS in the air system; proper fuel pressure, proper timing. An Induction Service is a profit center for a mechanic. That is not to say there are times when carbon buildup is a problem and should be addressed, but it's not routine service. It also won't fix pinging if the timing is wrong, or fix a bad idle if the problem is an air leak.
I've always had very good luck with Gislaved Nordforst tires. I have heard nothing but good about the Nokia, and folks report that the Nokia are slightly better, but I have no experience with them.
Good luck!
