"So good" is not typically something you see when people are talking about Brown Turkey. Unless you think sweet and watery figs are good. I'd be interested to see pictures of the fully ripe fruit, both whole and cut in half longways.
1) Most guys avoid heating pads. Putting them on top of your fridge is usually sufficient, as long as temps stay above 55º-60º, they should strike and root just fine. 70º is ideal for my rooting trials, and anything over 80º is overkill or detrimental to rooting. The only time I've ever used a heating pad was during the ice storms we had in Atlanta a couple years ago, and it was under the outside of the plastic bin, and all of my figs were an inch off the floor so the cups or bags never came in contact with the actual pad. Opinions vary on that one.
2) See #1. I'd add that I kept mine on a timer and kicked it on for a half hour, off for a half hour. I was just using a typical bed/medical heating pad, though.
3) There is a plethora of rooting info here at the forum and at the main Figs4Fun website - have you read it? Start here, with the top entry: http://figs4fun.com/Growing_Tips.html
3a) Grow lamp... overkill. Figs are practically weeds. They don't require special treatment. A little humidity, a generally clean environment, a stable temperature, and NOT overwatering the soil you're rooting them in. Get those right and you're good to go.
65º is fine - this is the ambient temp in my house during winter. Above the fridge or inside the entertainment center (with my STB, Tivo, etc.) usually stays warmer, so does the laundry room. Get creative and don't get stuck in this mindset that it's so rigid. Again, figs are virtual weeds. They don't like to be babied. You'll ruin more by caring too much than you will by not caring enough. There isn't any hardcore science, and if you can get to a 30%-50% success rate on rooting, you're doing better than many.
Don't think about it so hard and you'll do just fine.
