Final Fantasy Hacktics

I have a few things I want to look into doing and I wasn't sure if I should make a different topic for each or just put them all in one topic. Please let me know and I'll gladly change things.

Anyway, I'm looking for help on the following subjects. I'm not exactly looking for just the solution (though I would be grateful for it), I would like to know how each step of the solution was made so I could apply it to other, similar things. If someone would like to simply point to a guide(s) that tells me what I need to know, that would be fine, too.

1) I like how WotL has the bonus battles with Algus returning. I'd like to add him to one of the undead battles in the PSX game. From what I've seen, it should just be a matter of creating a class with Undead innate and then assigning Algus's sprites to it, but I want to know if there's more to it than that.

2) I know this will be tricky, but I'd like to add a Turn Undead ability for Priests. So I need to know how to add (or replace) an ability, add a formula (I'd like it to hit only undead Faith% of the time and reduce the target's Brave by MA+Y), and set it so the Priest is in standard casting animation while the enemies hit have the effect of Holy Explosion (I'm not looking to add new animations at this point).

3) Is it possible to make Class Evasion apply to both physical and magical attacks?

4) FFTPatcher has the Dark Knight abilities from WotL available in the abilities list. Am I able to just add them to a job's ability list or would additional hacking be needed?

5) Is there a way to make the Charge attacks target a unit and only work when a bow, crossbow, or gun is equipped?

Is it possible to make Weapon Guard a support ability rather than a reaction ability so that a unit can use another reaction ability with it? If so, how hard would it be and what (in general) would I need to do?

I noticed in FFTPatcher there's an option next to every ability to set what kind it is. Is it that simple? If so, I'll be quite happy.

I've searched here and I've checked the wiki, but I'm still not sure what the difference is between Vertical Fixed and Vertical Tolerance and when I should or shouldn't have them checked. Could someone please explain them to me?

I have a few questions regarding FFTPatcher that I haven't been able to find searching here or reading the tutorial wiki.

1 - In the Abilities editor in the AI section, what does "Vertical Increase" do? It's missing from the list on the Wiki.
2 - In order to make the computer use an ability it wouldn't normally use (Ramza's Scream, for example) do I simply check "Used by Enemies" and makes sure "Target Enemies/Allies" is checked in the AI section?
3 - When editing the ENTD there's a number input next to the "Jobs Unlocked" list. I know it affects job level, but does it affect just the base job's level or whatever job is in the "Jobs Unlocked" list? Also, the highest job level is 8, yet I can input any number from 0-255 (00-FF, I know). What, if anything, happens if I put a number higher than 8? Would having "Mime" and 255 as entries create a character that knows all job abilities?
4 - Selecting "Random" in the War Trophy list doesn't seem to give me anything after the battle. Does it not work, or is there something else I need to do?
5 - Does anyone know of a GUI-based program that can edit which shops sell which items? The one in FFTPatcher doesn't seem to work.
6 - Is there a guide that goes down FFTP's abilities list and describe what each of them does?

I apologize in advance if any of these are redundant questions. Feel free to point out the topic with the answers if there already is one. Thanks in advance for any answers and/or help.
