I vote for ADA Amazonia. It's amazing what a difference it can make to the plants. You use it straight out of the bag. There is an ammonia spike for a few weeks but if you plant heavily the plants will love it and become established quickly.
I have mixed the above with flourite, just to try to cut costs and stretch it. It's not as good for the plants but will work.
I would not do the substrate heater. They are costly and unnecessary. There are those that say they are even harmful to the plant roots. At any rate you don't need it, so save your money for your substrate.
