IDHMBWM - but I remember a PrC in one of the dragons that combined the barbarian and sorcerer to great effect - you could cast while raging and your spells got even more powerful.
Also consider Shield charging Paladin (feats from DotF) with Sorcerer levels - great synergy.
Do not overlook power of wizard over sorcerer. While the sorcerer can cast more per day than the wizard. The wizard gets that very nifty and often dismissed/overlooked ability to scribe scrolls. As a wizard your goal is to get as much money as possible because more money equals more scrolls. Combining aa few levels of wizard with other fighting classes can be extremely powerful because of the sheer number of options available with the low level spells.
For PrC's, go with Spellsword, Bladesinger, the Dragon mag one, or Sacred Exorcist. If I am not mistaken, sacred exorcist is the only PrC that gives 3/4 bab with a spell level at every level that can be used with arcane casters.
My recommendation is to take all levels in wizard until you can qualify for the SpellSword PrC, then take levels in Spell Sword until you can qualify for the Sacred Exorcist. Again, IDHMBWM - you may need to take a few levels of fighter/paladin, but regardless, focus more on wizard levels as your spell casting progression will greatly enhance your fighting prowess. Once you can qualify for the Spell sword PrC take enough levels to raise your casting level so that you can cast dismissal. Then take the rest as Sacred Exorcist levels. Your BAB will be phenominal considering your spellcasting potential. I am pretty sure you will be able to cast 8th level spells (possibly seventh). Regardless that is enough to get Tensor's Transformation and divine power via limited wish. Not to mention you will be able to turn minor undead (but more importantly can now qualify for some of the feats in DotF - like the shield feats).
Good luck.
