So I've only been behind the torch for 2 months so take this with a grain of salt. These are all typical questions and their is tons of info on here that cover all your questions.
1. Your ventilation seems adequate but also depends on the size of your bench area. http://www.talkglass.com/forum/showt...entilation-101

2. It's inevitable you will burn yourself but you can prevent some of it by keeping a clean work space and always keep hot ends of glass away from you when laying them down.

3. I would personally do a bunch of clear till you get shaping down then move to fuming. Color is expensive save it.
4. Personally don't know how to tell the difference but looks like you got a killer deal on your kiln.
5. I went with Schott artistic from ust glass. Super helpful and great deals on cases.
6. Propane absolutely outside and be sure to chain your oxygen.
7. I use 26x4 for basic spoons and chillums larger like 38mm for ISO spoons. There are some great threads on here about glass sizes.

Def use the search button and just scroll and read. Also don't forget I'm also new so take this with a grain of salt. Good luck on your journey!
