I'm going to be gentle here, but almost all of your questions you could have found the answer either by using search, or by taking your time to consume the entire thread.
Yes, we realize it's a lot of work and quite a bit of stuff to read. Surely you see the problem though of making the thread even harder to look through for everyone else by adding beginners questions to it.
Users here are expected to help themselves first by looking through all the excellant information provided. It's out there, you just have to find it.
I have a few questions. I used to play hunter and tankadin and now I'm playing SP. There are some things that confuse me thou.
Innerfocus is a nice crit bonus and some good mana saving. Where should I use it thou? My first reaction would be on SW:P since that one stays all fight long. During fight I would link it to VT since that is our biggest dmg dealer but on forums I read MF gives better results. Why? I also see MB giving slightly worse results then MB. I also read that combining it with mind sear is best.
Question: What is the optimal combination with IF considering no mana issues?
Question: What mechanic did I miss that MF would get better results then VT? Or is that forum plain stupid?
Second problem I have are groups. When to sear? When to combine sear and DoT's? When to ignore sear? Emalon gives me low DPS if I switch to the add. On razorscale I'm not sure if I should sear or not.
Question: How many mobs would be needed so mindsearing all the way is best? When combine it with DoT's?
Question: Is the glyph of mind sear worth it?
Question: Does mind sear break CC?
Third problem is the balance between crit and haste, the stacking of crit, soft crit caps, the stacking of haste, haste caps and a 2MF/MB haste barrier.
I used to play hunter and I know my perfect speed back then for a 3:2 macro was 1.9. Do those things excist for shadowpriests? What should I aim for? How does clipping MF's trade off with loss of SP/crit?
People tend to prefer crit to keep their glyph buff up. Is there some kind of soft cap where we reach 98% average uptime?
Question: Is there a softcap in crit to keep the glyph active? How much?
Question: Can someone explain the 2MF/MB barrier if it excists?
Question: How should I trade off haste vs crit? Keep it balance? Favour one of them slightly?
