Ya. The ONLY difference in the i7's and i5's are i7's have hyperthreading, which games don't really use that I know of. If you are into work related tasks, get the i7. Other wise just save yourself 100 bucks and grab a very capable i5.

The i7 also has a larger cache (8 MB instead of 6 MB for the desktop versions).
Wikipedia has pretty good lists of exact features of each CPU, by model number. Intel's lists are more thorough, but each CPU has a separate page. Wikipedia puts it all on one page.

Yes by that followed by the numbers following the i5. Higher is better, same as in graphics card series numbers.

Take for example, the i5 3570K.
The 3 means its in the 3rd generation family. If the first number is higher or lower, its from a different architecture or manufacturing process.
The last 3 numbers show which processor it is. The lowest in the Ivy Bridge i5s (3rd gen) is the 3330 and highest 3570.
The K is the suffix. K means it has an unlocked multiplier for overclocking. There are a few more variants, but its not too common on the market.
Across generations (2500K -> 3570K -> 4670K), the performance difference is around 10%. But there are quite a few things that change.

That isn't strictly true. The Sandy Bridge i7s are i7-2xxx, except the Sandy Bridge-E versions which are i7-3xxx. Likewise Ivy bridge is i7-3xxx, except the Ivy Bridge-E versions which are i7-4xxx.
The K versions also have the faster mobile iGPU, but are missing TXT, VT-d, and vPro. Generally only businesses care about TXT (trusted computing), and vPro is of questionable efficacy (supposed to make video playback clearer). But lack of VT-d really hurts if you run virtual machines (it allows VMs to have direct hardware I/O access).
