First: an actual answer for rumble (yes, I know he played his game, and by now is roleplaying the repercussions of his Tele-train, but somewheres there is a brand new player, with the exact same question, so they will be by proxy the new rumble), the best honest way is to take a level dip in Maester (complete adventurer), it's a fair shake more than taking a feat, but with cutting your time by half, I'd say it's worth it, then get a Dedicated Wright (Eberron Campaign Setting) he can craft for you, but only one item at a time.
Secondly: for the Mozzarella Madness, instead of being a cleric, use an artificer; not only do you get the half-level of xps, but you'd get tasty craft reserves along with it. It'd cost less for the base cost of the scroll of grater restoration than you'd get in reserve, 91 vs 1200 (and that's assuming you bounce between 14 & 15, technically artificers could create the scroll at 13), plus, all the crap you crank out with all this level whittling, an artificer can reclaim essence it all back into a large lump sum of craft reserves to build something big.
Thirdly: on to Gouda! Third party Sword and Sorcery's Book of Eldritch Might III has an item creation feat 'life to the inanimate' where you pay extra gold/xps and make your magic item intelligent, included are rules on levelling intelligent magical items (and not like legacy items, they specifically don't gain experience with you through adventure, someone has to donate experience, at 25% per level), so for 2940 xp, you could make a dedicated wright that was a 5th level artificer on it's own (that's 2500 for lvl 5, 80 for sight with darkvision, 200 for telepathy by touch, and 160 for the basic Wright). Make multiple of these Super Wrights stick em along in a chain (hence the telepathy by touch) and you can get an assembly line factory of magical items, all powered by craft reserves.
Lastly: for those that don't like cheese, an easy fix is declare when the greater restoration hits, all the little wayward xps are drawn back to the character, so all items created with left-over bits of xp loose their magical properties
.... but, c'mon, who doesn't like Kraft Cheese....
