OK, as far as updating the stats go, I'm done.
Shopping list under spoilers.
(And yes, I basically went down the list of magic items by price on the MIC and got the most interesting stuff. Probably some overlap there. Also, I had no clue how to handle the "vanilla" items like enhancement bonuses to attributes and whatnot...)
For enhancement bonuses to armor and weapons, we're not including those in the cost of Wishing for things, IIRC. You just get an enhancement bonus that scales with your level, and that bonus should be +3 right now, since it is rounded
up.
For stat boosters, skill boosters, etc, just use the price of the cheapest one in the DMG. So an item that adds an enhancement bonus to your Int would cost 4,000 gp (the cost of a Headband of Intellect +2, the cheapest version in the DMG).
You can just add items together with no increase in cost for combining them, or for what slots they take up, etc.
I think everything on your list will count as an attuned item except your sword, which doesn't have a continuous effect IIRC. So you'll have to decide how to combine those items into the 8 you want to keep attuned most of the time, and which ones will instead just be sitting around in your Enveloping Pit (or whatever) till you need them.
And those Caduceus Bracers are for paladins. What are you going to do with them? Did you copy the wrong name down?
Also, don't forget that you can add +5 inherent bonuses to any (or all) your ability scores, if you want.
