Wireless and graphics questions (and coupons...?)

So, I have a few tiny loose ends to tie up before I order my laptop.

Wireless G and Wireless N. What is the difference? I know that N supports faster speeds and have heard that it's likely going to become more of a standard in the future. My question is, will it work like any other wireless device? I don't want to get it and find out it needs some sort of special connection.

Also, graphics cards. I see a whole lot of debate about this here, and not really a 100% clear answer to anything. I'll be using Photoshop and other digital art programs, and running Windows 7. I don't do serious computer gaming, and the most 3D-intensive game I might ever run would be something like the Sims- and that's an "if".

Would dedicated graphics have any significant advantage for me? I've been configuring with the Intel, but I don't want to sell myself short and regret it later, especially with something that can't be changed.

On the other hand, it's also important to me to have a cool-running computer, so if the added heat and power consumption will outweigh the benefits it'll probably be a deal breaker.

Help clearing that up for good would be absolutely great.

And for the last matter, are there any good coupons out right now? NBR's page still only has that $30 off one. I've been waiting for something decent to come back around, but I'm going to place my order tomorrow regardless. I'd like to make sure everything's running smoothly before I take it to school, and ideally have it before I leave the state for two weeks.

 

dude first off use the $250 coupon it adds with the instant rebate= 30% off maybe a little more i cant remember.

About the wireless card, Wireless N supports a/b/g/n
The graphic card its up to you i say upgrade to the fullest extent because in the long run you will need it there is no turning back once u choose ur graphic card you cant upgrade it in the future.
