are you asking for advice on building a sorcerer, or advice on building your party's first 'true caster'?
if you just want to make a sorc:
personally, i think crossblooded is a trap... -2 to Will saves (and no real need to prioritize Wis) leaves you with basically 0 good saves, and losing 1 spell known/spell level means that even though you gain new spell levels every even level you'll know 0 spells of that level until you level again (so, at 6th level, for example, you gain 3 third level spells/day but you know 0 3rd level spells so you can't actually cast a 3rd level spells until you learn one at 7th... unless you take a metamagic feat just to make 1st or 2nd level spells into 3rd level spells, but then they'll take a full round action to cast). you're better off spending feats for the Eldritch Heritage line if you want powers from 2 bloodlines. crossblooded is really only good (IMHO) for dipping if you're optimizing a blaster wizard (the arcana benefits from 1 level of elemental/draconic sorcerer can be a pretty big boost for an evocation wizard).
i'd suggest choosing one bloodline that supports the kind of caster you want to be and jusr running with it. sorc is easier to use than wiz because you only need to really understand/remember the spells you know instead of everything in your spellbook, and you don't need to worry about preparing spells each day. the flipside of that coin is that your selection of spells known is very important... don't overload on any one type of spells- go for a mix of blasts, utility, buffs, and control. and when you see a spell that you feel like you really want to have "just in case" but know you won't use very often at all, remember that you can buy scrolls for just such occasions.
if you're interested in other caster advice:
let us know... i'd suggest one or two other options if you're open to them, and i suspect others would as well.
I am willing to give about anything a whirl. I and my GM am hoping to have a successful caster will spark interest in making more in future adventures so he is my corner on making this character as awesome without going crazy.
