Howdy pardner,
made it into the sacred halls of PC gaming just recently, too, and had my first weekend playing it.
I'm also on a Laptop, i7-Q2670m, 6770m, so slightly better but yet comparable specs.
Definetly get
Fallout Mod Manager, the
Mod Configuration Menu and the
FVSE Script Extender, with the 4gb enabler located on the same siteConcerning the visual enhancers, you have to look carefully what to install.
Some of the weather mods and texture packs are extremely taxing on the Graphics Card, and mobile GPUs like yours or mine are no GTX580s.
I've tried out
Project Reality, and it is arguably the best looking weather mod, using an incredible skybox, and comes with a number of cool effects like HeatHaze, dynamic DoF and peripheral Motion Blur.
Sadly, it absolutely killed my FPS. I got 8-20 FPS with it activated, and 45-60 without it.
So go with Lobotomites suggestion and get
Nevada Skies. That mod didn't hit my system at all.
In general, it has a very vibrant feel with warm and saturated colours.
Use that mod here to change its looks at your leisure
Electro City Imaginator

One thing you'll also need when playing with Nevada Skies is this
Flashlight NVSE
http://newvegas.nexusmods.com/downloads/file.php?id=39968
As the name inidcates, this adds some flashlights to the game.
And with the darker nights of Nevada Skies (or any other dark night mod), you *will* need those.
Also, leave your fingers off Texture Packs with 4096x4096 textures.
This thing here makes the wasteland prettier and doesn't hit your system too hard.
Poco Bueno Texture Pack

And at last a mod, that adds a lot of fixed to the game, plenty of new items, even some locations and a re-balancing of a lot of enemies(=made much harder)

Have fun, I played through the game 5 times on the PS3, and still, playing it with all these enhancers @ around 50fps in average is such a blast.
