1. Hard to find a better one for $60.
2. If you drop the SSD, yes, you can switch to LGA 1366 and stay within budget. I would recommend doing this because you can always add an SSD later. Switching from LGA 1156 to LGA 1366 would require a new CPU, new RAM, and a new mobo.
3. A 5850 is perfectly fine for 1920x1080. Don't spend an extra ~$100+ for a 5-10% performance increase.
4. No, $220 for an 80GB is normal. But IMO SSDs in general are overpriced ATM. Wait a year or two to see if prices fall.
5. No, the SSD is probably not worth it with your budget. Since the TV costs $610, the remaining $1500 should be put towards the essential core components like CPU and graphics card. If you find a few combos and have money to spare, shoot for an SSD if you want. Just don't make it a priority.
6. Unless you listed the wrong SSD, that Intel SSD is NOT faster. It has 250MB/s read and 70MB/s write; the Corsair has 250MB/s read and 110MB/s write. Also, it costs $35 more. I'm not sure what you're looking at.
7. The Blu-Ray drive you listed IS worth it. It's a combo drive, basically a Blu-Ray reader and a DVD burner put together. At $100, it's not that bad, though you probably can find a $60 BR reader and $25 DVD burner. Silvune said that BR burners are not worth the price yet; this is true.
8. Every review you've looked at must be pre-500GB-per-platter HDDs. Samsung F3's are the drives to get, and if they're out of stock, Seagate 7200.12s aren't bad either. 500GB-per-platter means 500GB HDDs are single-platter; 1TB, double-platter; etc. This means they run faster and cooler, and are more power efficient. Bottom line: WD is falling behind. That 1TB used to be the fastest.
