I'm assuming you want something that is mostly rogue with some combat capability.
There are a couple of different ways to do a combat Rogue that work well.
Going with an archer, all you really need is high Dex and Int. Not has much need for Con, although it is still very useful. This is the easiest way to do it. Make sure you have Precise Shot so you can shoot into melee.
Going with a melee rogue, you will want higher Con and Str than otherwise. You still want a Dex and Int. Here is where you are going to want a lot of tumble skill, so you can maneuver in melee.
In any case, I would suggest mixing it up with some Fighter levels. At 7th level, I would probably be looking at Ro6/Fi1. By level 20, you want at least 4 levels of fighter for the extra attacks, seriously consider 6 levels of fighter.
I'm not too fond of feint because it uses up an action. Instead, look at getting a Wand or Ring of Blinking and activate that when you need your sneak attack.
There are so many ways to build a rogue, it would help somewhat if you could describe what you are looking to get out of the rogue skill set.
