"Send in the Dwarf" is always a good strategy, but if you take the Improved Initiative feat and have likely high Dex, you will more often than not act before him. Area control spells do exactly that - control an area. If said Dwarf charges into the area of your spell, well, that is his choice. You can try and arrange for the Dwarf to delay his action until after you cast your spell, but hey, that's between you and the the other player.
Don't assume the Chaos in Chaotic Good means "act randomly":

"Chaos" implies freedom, adaptability, and flexibility. On the downside, chaos can include recklessness, resentment toward legitimate authority, arbitrary actions, and irresponsibility.
You do what works, and adapt your tactics when what you're doing isn't working. Being reckless means you may not always make the most tactical choices, but if your teammates are ALSO reckless, well, let the dice fall where they may.
A sorcerer, by design, is more typically a blaster than a melee combatant. Is there a specific reason you want to mix it up with the warriors? A few levels of Rogue would be the ticket if that is the play style you wish. Sneak Attack does apply to both ranged and melee touch attacks, and Evasion is never a bad thing. You can use your Sorcerer spells to somehow deny AC to your foes, or get your Barbarian fella to knock opponents on their butts, and Sneak Attack away from a safe (up to 30') distance.
Keep in mind, however, that the Sorcerer is generally a feat-starved class, and you may want to invest in a few combat-related feats to improve your melee (especially Weapon Finesse and Two-Weapon Fighting, assuming you have a high enough Dex). It might be worth a 2-level dip into Fighter to get those feats over Rogue's Sneak Attack schtick. You get armor proficiency, 2d10 of juicy HP, and you could even wield a reach weapon from a safe distance.
Now, on these boards, most players cry foul when multi-classing spellcasters because casters "lose" spell levels, effectively denying yourself access to your highest level abilities. To them, I say poo. I'm of the opinion that if you're already choosing to multi-class, you don't care about highest level spells; you want utility over raw power. Good news! With 2 levels of Fighter, you can still get access to 9th level spells when you hit character level 20. If you're like me, though, you doubt you'll ever see that high of a level.
