OP, forget about ssds with your budget, I dont even know why these guys keep pulling it up.
Now to address a few of your issues. First the usb3/sata3 stuff. now, are you even going to get a hdd with sata3? if not then you can ignore that. what about usb3 devices, do you have any right now? no? forget about that as well. Even if you do end up really needing usb3 just get a usb3 card and chuck it in your pc.
Second, for you all motherboards are practically the same. There are no "good" motherboards you can get for your purpose, they all work as they intend to and are pretty much of muchness. Just stick the the major brands and buy a low end one and you should be fine.
And why are you getting an i5 760? For exactly the same price you can get yourself an i5-2500 and it performs much better. you'll need a p67 (1155) board, I'll suggest getting an matx board as its smaller and can fit in more compact cases.
And lastly, psu: always get one with 80+ efficiency. And around 400~500W for your pc. If its your first time building maybe get a modular, its a bit more expensive but a lot cleaner and much easier to install.
