Okay, first off those warranties are a complete waste of money. They may give you piece of mind but chances are very good that you will never use them. There's also the fact that integrated graphics are not good to game on, at all. Plants vs Zombies would be okay, but if SWTOR ran at all, I couldn't imagine it being a very fun play. Plus you can just find better deals on laptops on newegg...
Here are my three suggestions for you...

This is hands down the most powerful of the 3. It has an i5 with 2.4 Ghz frequency and 4 Gb of Ram. What makes this computer so special is the graphics card. It has a 6650m with 2Gb of dedicated memory. That is going to get you the best gaming out of the three by far. Plus, it has the best resolution 1600x900. Now where this computer kind of falls off for you is that it's a 17" inch screen and weighs 7 pounds. So it is the biggest and the heaviest. I know gaming isn't your largest priority here, but if you're willing to overlook that it's the least mobile of the options this is the one for you.

This one is the cheapest and most underpowered of the three. It's rocking an i3, 4Gb of memory, and a 520m with 1Gb video memory. You're basically taking a performance hit across the entire board to get a more mobile solution. It's a 15.6" screen with a resolution of 1366 x 768. I can't testify how well this could play SWTOR, but it certainly would be on lower settings. If you're looking for the lightest and cheapest, while still getting the job done, this is the way to go.

This is the middle of the road computer. It has an i5, 4 Gb of memory, and a 6470m graphics with 1Gb of video memory. That video card is not on the same level as the 6650m but is much better than the 520m. It's a small one with the 15.6" screen and a 1366x768 resolution. The only thing about it is that it's by far the most expensive at over $800.
So, a summary if some of this went over your head.
#1 Most powerful by far, but biggest and heaviest.
#2 Lightest and cheapest, but you take a performance hit
#3 Middle of the road, but most expensive by far.
