A rogue who has selected the 'minor magic' or 'Major Majic' may refill this staff with his minor magic (1 charge) and 'Major Magic' (2 charges) may activate this staff for the following abilities.
2 Charges: Pass without trace.
3 Charges: Invisibility.
5 Charges: Greater Invisibility
Cost:
400*4*11 / 3+300*2*11 / 5 + 200 * 1 * 11 / 2
400gp * 4 * 11 / 3
300gp * 2 * 11 / 5
200gp * 1 * 11 / 2
10,120GP Base cost.
Unlike other staves, once per day this staff can be refilled using a 0th level spell, provided that spall came from the 'Minor Magic'. Additionally, expending a use of the 'Major Magic' talent refills a single charge as normal for a 1st level spell, even if that spell does not appear on the list of spells the stave is capable of casting.
(Cost, 1,500 for heighten spell, I was unable to cost major magic as a charge option, but I don't think it should alter the staves cost as it could be a viable charge option anyway)
Cost source: 1/3rd of a single level spell bump (eg: silent spell, for heighten), * 1.5 for including it into a pre-existing item 1/day.
Base cost so far, 11,570gp + the cost of the 'variable charge' ability... though I am tempted to leave it at 11,570
I'm also likely to restrict it to nonlawful alignments (absent a UMD check) for an additional 10% discount, as per magic item creation.
Unfortunate drawback: cannot be used to fuel arcanists consume items ability as it takes 2 charges for a single spell to be released. Then again, the item is intended for rogues with UMD.

Okay, it's best to arrange the spells by spell level, then set the minimum caster level based on the highest level spell (you can go higher). There are no expensive material components or foci so that simplifies the calculations.
Grtr Invis ($400*4*8)*1 /2 = $6400 {highest spell level gets the 100%}{CL is >=8 with staves}
Invis ($400*2*8)*.75 /3 = $1600 {next highest the 75%}
Pss w/o Trc ($400*1*8)*.5 /5 = $ 320 {rest at 50%}
total base cost = $8320
at 11th Caster Level it would be $8800 +2200 +440 = $11440
You have to recharge with the same spell otherwise it's a great advantage. Recharging with a 0 level spell into a 1, 2, or 4th level spell is crazy good, so +$10000 cost minimum.
The discount is for a specific alignment is 30% (1 out of 9 alignments). Discount for 6 out of 9 alignments (non-lawful) I'd estimate at 5%.
Item requires a specific class, 30% discount.
Not having to use UMD to activate... I would estimate base cost per charge from 400 to (1000 to 1800{recharges 1/d}). This will roughly triple the base cost of the item.
So the cost went crazy because of some of the things.
I'd price out spell storing ioun stones for a once a day casting, then halve the total cost (ioun stones are at *2 cost due to the no slot). That would be a good comparator. Of course your non-caster is going to have to pay an NPC to recharge the spell store item.
