I'll answer the posting questions...
First you embed pictures in a post by using the camera tool in the posting toolbar. You png did not appear although your link was valid.
No there is no preview.
Those are on the high side. Short term probably not that harmful, but long term they will be killing. In an ideal world a drive shouldn't get much above 45C. Your CPU temps aren't great either. You could bring them down by using smcFan Control and running a small fan at the back of the computer.
Here's my setup using a $10 clip-on fan mounted to a bracket on the wall behind the computer, to avoid vibration. The fan blades are about 6" from the back, and the fan is aimed at the the upper left, in particular, but covers most of the area of the back. I turn it off and on using a power cord inline switch to avoid wearing out the cheap switch on the fan itself. Even in summer, while the back may get warm, it never gets really hot to the touch.
I periodically open the fan up, clean the blades and lubricate the front and rear shafts with a light oil.
Here's a link to a thread with some posts of mine on using smcFan.
And some temps running smcFan. Note: Power Supply Position 2 will read lower than Postion 1, which is nearer the PS.
