The rogue in our group has a 15 str, a 16 Int... although, she has a high dex as well (hey, she rolled well!). She focused on skill choices, and her strength has come in handy multiple times so far.
She didn't focus on power attack, though, but used her high dex to make her ranged attacks better.
In combat, you should focus on power attack, coupled with a two-handed weapon. As a rogue, your choices are limited, so I'd just go with a spear (plus, you can throw it). Javelins and daggers are great choices for your ranged weapon; avoid crossbows.
The high int means you can take a smattering of skills beyond your essential skills. Were it me, I'd make sure I spent two or three skill points a level on different skills, like forgery, knowledge/local, appraise, and the like, so that when the GM makes that annual "make an appraise check" or "make a handle animal check" you're prepared.
Really, I think high int and str are GREAT for rogues, although I would think Dex is more important overall.
Your disable device must be through the roof -which is always good (why play a rogue if you suck at finding/disabling traps?). Any of those skill-boosting feats that improves your search or disable device checks would be great - keep your numbers high, and become the awesome trap-disabler!
