My first build - looking for any advice or critique!

As I'm heading off to college next year and my current computer is an offensively slow 1.25 Ghz eMac, I've decided to finally splurge and build myself a nice new gaming and multimedia PC to last me through school (or at least the next three years) with little or no need to upgrade. However, as I've always used Macs, I have almost no clue about PCs, and while I've spent many tens of hours reading up on how to build one, I'm still looking for help.

Basic Facts
1) It will be used for fairly heavy gaming, plenty of Photoshop, and, as I will be doing a game design major, possibly everything from video encoding to 3D rendering. It will run 64-bit Vista and Ubuntu.
2) I have a budget of about $1400, counting speakers and monitor. Tax (approx. $100 total) and shipping (approx. $40) are not included in the component prices. Rebates are mentioned but not deducted from the base prices.
3) I live in the San Francisco Bay Area, California.
4) I have to buy everything, and I mean everything, from scratch.
5) I have no parts to reuse.
6) I am not planning on overclocking presently, but likely will in a year or two's time.
7) I'm planning on getting an LCD, about 20", to run this and my PS3.
8) I plan on building this somewhere around late February to March, in the hopes that Nvidia's new GPUs will drive prices down a bit.
9) I need a mobo with gigabit LAN, good onboard audio, and the rest, but nothing fancy like Crossfire.

My Shopping List - All prices are taken from Newegg, but a few things (namely speakers and monitor) I'll buy from Amazon or a brick and mortar store.

Specific Questions
1) Will the Earthwatts 500w be enough to power this whole rig? The GPU, with its Dark Knight cooler, especially worries me, as I know nothing about calculating wattage but I have a feeling this requires a lot (graphs I've seen seem to place the 4870s anywhere between 180w and over 300w). Other forums have told me it is good enough, though.
2) Will the Sonata, with its rear 120mm fan, the Silverstone 120mm, the PSU fan, the Dark Knight GPU cooler, and the Zalman CPU heatsink/fan be able to keep this cool enough?
3) This is a very nooby question, but will the mobo be able to control the case fans and the Zalman or will I have to control them with the voltage/fan controller?
4) I'm planning on using Arctic Silver 5 on my CPU and the Zalman, but as I don't think the Zalman comes with its own thermal compound already on it, will I need AS's thermal material remover and surface purifier, or will a rubdown with alcohol be fine?
5) Does anyone know much about that Acer monitor? I haven't seen it in person or read any "real" reviews, but it has good Newegg feedback. I was wondering how it compares to this Asus VH222H, which is similar (and with audio-out, a big plus) but with a hideous orange powerLED.

Any other comments on the build would be greatly appreciated. As I said, I am a complete newby to PC building, and no comment is too mundane and obvious to be helpful.

Thanks in advance!

You did a great job there.

I agree with sharken, get rid of the Zalman cooler.

Yes the Earthwatts 500w be enough to power this whole rig.

Yes it will be cool enough, at least until you overclock the CPU. The HD 4870 will kick most of the hot air out the back of the case through a vent.

Go with DDR2 800 instead, you can grab 2 of these for just a few bucks more (before MIR)

and as mentioned before drop the Zalman cooler, as there are better out there.

Will DDR2 800 work as well with that mobo, though, which lists 1066 as its standard? My uncle (a programmer) suggested sticking with the standard memory speed of the motherboard just to simplify things. Still, 2x the RAM is certainly something to consider.

Following some recommendations on other forums, I've decided to ditch the Zalman in favor of a Xigmatek HDT-S1283 with retention bracket, too. Cheaper and better, it seems.

I was sort of hoping that the new Nvidia cards would drop prices on the 4870, too. I'll see what happens over the next few weeks, though. It is worth pointing out that that particular 4870, the Asus EAH4870 Dark Knight cooler edition, is actually much cheaper ($40 before rebate, $60 after) than most GTX 260 216s right now.
