Yanfly, fox's and Muteday's Job Point plugins

I'm just totally confused with these.

From what I'm getting from Yanfly's, Fox's, and Muteday's plugins is that they won't exactly do what I want it to do, that is:

I want each class to have a separate job level with a separate max level and exp required based on what rank/tier job it is.

Also, if I'm reading these plugins right, JP will be treated as exp but if so, I don't get any JP to spend, unless I re-spend it after I earned it?

What I want to happen is each class has a required Exp each level, but you gain 1 JP -to spend each time you level it, not spending the same exp as currency for skills- per level gained per class, and different classes have different exp amounts required to max, and also different amounts of JP acquired to use up.

I'm going for a more Ragnarok Online job system, such as Novice->Tier 1 jobs->Tier 2 jobs. So The base class every character has is a tiny job level max (10) and tiny JP pool (10), and low exp curve [90, 180, 270, 400, 530, 660, 900, 1140, and 1500]. where tier 1 and tier 2 jobs have bigger max levels and more JP (50 and 100 respectively for Jlevel and JP) to use respectively.

How do I use these series of plugins in tandem to get my results I need?
