Help a newbie out with understanding these SMART values? And upgrading!

I'm pretty dumb and I'm not entirely sure if these are good values for my hard drives. SmartCTL says they are, but I want to be sure since I'm thinking of upgrading my SSD and at least one of my storage drives, and aren't entirely certain I'll choose the right ones to retire (or move to externals.)

I have four drives:
A "PNY XLR8 SATA 120GB 6Gbps 2.5-Inch Solid State Drive SSD9SC120GMDF-RB", which is my main OS drive;
A Seagate Barracuda 7200.11 (ST3500320AS) 500 GB drive which I use for storage (and doesn't get used or turned on much);
A 640 GB Caviar Black (WD6401AALS-00L3B2) which is used as a Steam and storage drive;
And a 1 TB Samsung Spinpoint HD103SJ, which is my main storage drive.

The SSD is almost two years old now, and the other drives are much older. The Caviar Black works well, and it's turned on most of the time because of Steam. The Barracuda isn't used much and stays powered down most of the time. And the Samsung Spinpoint is used a few times a day (I mostly use it for music storage.)

I ran GSmartControl to get SMART logs from all four of the drives, which I've attached. SmartCTL says the Barracuda and the Caviar are okay, but the Spinpoint shows some ATA errors, which I'm not sure about. SmartCTL says it's fine, but I don't know. And the SSD... Speccy says the drive is bad because of two Reallocated Sectors, but SmartCTL says the drive is okay., so...? Eh?

And if anyone has suggestions on what drives to get, I'd appreciate it. I want to upgrade the SSD to a 240 GB one, maybe replace the Spinpoint and the 'Cuda, and make the Caviar Black into a music storage drive.

Sorry for the rambling, thanks in advance for any advice you can give. :)
