Alright, Grek, I'll let you apply the Battle Sorcerer variant to a wizard.
You hit die is now a d8 instead of d4. You get your max HD at level 1, and on all subsequent levels you can either roll (during a session) or take the average (which is HD/2 +1). You'll probably want to recalculate your hp.
You know get cleric attack progression
Since you don't have bluff as a class skill to give up, you do not get intimidate as a class skill (if you really want intimidate, then you can limit yourself to only having knowledge(arcana) as a class skill, and all other class skills will be cross-class for you)
equipment proficiency as battle sorcerer
You can cast one less spell of every spell level per day
At level one, you start with a spellbook containing all lvl-0 spells, and 2 + IntMod lvl-1 spells. At level 2, you get 2 more lvl-1 spells. On all subsequent levels, you will learn two more spells, only one of which may be of the highest spell level you can cast.
So you should know 8 lvl-1 spells, only two of which you may have prepared at a time, and one must be a transmutation spell. The table on the page for wizards shows how many spells you can cast when you are that level, NOT how many MORE spells you can cast when you reach that level.
Also, bear in mind that your familiar only grants you alertness if it's within 5' of you, and only grants you your grapple bonus/empathic link up to 1 mile.
And Barbarossa has a point about grappling things bigger than you; sure, being huge size only grants you a hefty +12 grapple bonus, but the monster's grapple bonus was actually more like +20. Also it had a constrict attack, and poison, and 20 AC. So yeah. Did I mention it half-killed Maelrigar in one full attack?
Other than that, though, your sheet looks fine. See you Saturday! By the way everyone there is totally a session this Saturday.
