Now for your selected parts:
CPU: There is no Sany Bridge i5 with 3.2GHz. You can either get the i5-2400 (3.1GHz) or the i5-2500(k) (3.3GHz).
An if you get a new one, why not the current model: i5-3570k (Ivy Bridge, 3.4GHz)
Motherboard: With the limited information you gave i can not really say anything specific. "Asus 6Gb/s USB 3.0 LGA 1155" only tells me the following: It is not a H61 chipset. But it still can be: H67, P67, Z68, B75, Z77... (and few others that are not that common). That's like asking "How good is this car? It has 4 wheels and a 4 cylinder engine!"
Nevertheless, here are some suggestions of good motherboards:
Asrock z77 pro3 (cheap, but not SLI capable)
Asrock z77 extreme4
Asus P8Z77-V LK
Asus P8Z77-V
RAM: Your current motherboard/cpu supports triple channel memory. That's why you have such a "weird" amount of ram (3x2GB + 3x1GB = 9GB). But all socket 1155 motherboards/cpus (Sandy / Ivy Bridge) have dual channel. So the ram configuration should be always something like 2x2GB or 2x4GB or 4x2GB or 4x4GB. (There are also 8GB modules if you need absurd amounts of ram).
Which brings us to the next question: Why the hell would you need 24GB of ram? For the things you do, 8GB (e.g. 2x4GB) is more than enough. There is no current game which uses 8GB ram, and most even stay under 4GB. And even when you record/stream, you will not exceed 8GB.
SSD: Does Seagate even manufacture SSDs? I would advise to pick a model which has proven to be reliable. e.g. Crucial m4 or Samsung 830.
