Building i7-950 with HAF932 & Gigabyte UDR3 mobo: connector questions

I have attached a couple of pix.  Here are my questions:
I attached a CoolerMaster 212 Plus:  how tight do I make the locking screws (the x-clamp attached to the cooler)?  Seems like there is alot of play left in the screws, but the cooler doesn't move easily.

Also, confused about the connectors.  Some of the wires are marked + or minus; others are not.  So for the power switch, is orange plus?
For the reset switch, is blue plus?
For the HDD LED, which is plus, which is minus, red or white?

What is the AC'97 connector and where does it go on a Gigabyte mobo?
Same question for the HD AUDIO connector?

Final question, on the Gigabyte mobo, there are appears to be two power connectors: an 8 pin ATX_12V_2X connector, and an 24 pin ATX connector.  Do I connect both, or just one?  And if its just one, which one?
Thanks for any help!!

Both.

Switches don't matter which way they are plugged in.

The common colour is usually ground - negative.

For LEDs if they don't work one way reverse them and they will work.

"... how tight do I make the locking screws (the x-clamp attached to the cooler)?  Seems like there is alot of play left in the screws, but the cooler doesn't move easily. "  ==>  Hard to say without actually having one of the same coolers -- but the simple answer is TIGHT ... the cooler shouldn't move at all.    If it meets that criteria, you've got the screws tight enough.

... as for polarity ...

"... for the power switch, is orange plus? "  ==>  probably, but it doesn't matter -- the power switch simply shorts the two wires together.

"... For the reset switch, is blue plus? "  ==>  probably, but as with the power switch, it doesn't matter.

"... For the HDD LED, which is plus, which is minus, red or white? "  ==> Red is plus.   Note that if you connect these backwards, it won't hurt anything -- the LED just won't illuminate (so reverse the connections)

"... What is the AC'97 connector and where does it go on a Gigabyte mobo? "  ==>  Nowhere.    You have a choice of connecting the HD Audio connector or the AC '97 connector, depending on which is supported by your motherboard.    Your board supports HD Audio, so you use that connector.

"... Same question for the HD AUDIO connector? "  ==>  This is the one you connect -- the HD Audio header is on the rear of the board and is reasonably well marked.

"... there are appears to be two power connectors: an 8 pin ATX_12V_2X connector, and an 24 pin ATX connector.  Do I connect both, or just one?  And if its just one, which one?  "  ==> BOTH.   The ATX connector is obvious;  the 8-pin CPU power is close to the CPU socket.     Do NOT attempt to power up the system without having BOTH of these connected.

Here's the audio connector I referred to above -- the connector with 10 light pins on light green mounts just to the right of the "AUDIO" label.

Thanks Garycase!  I have 2 last questions before I fire this baby up.  The locations for the boot drive, DVD drive connections, and the memory.  I have attached 2 pix.  The instructions aren't clear in the book.  So I put 2 2 gig sticks nearest the CPU.  And I attached the boot drive to the 2nd white connector nearest the middle.  I attached the DVD to the middle blue connector.  Is this right or wrong?  Does it matter?  Thanks again!

The memory is wrong -- put one module in each of the first two white slots (the one closest to the CPU and the middle one).    You'd get better memory performance if you used THREE matching modules (in the 3 white slots), as the X58 chipset supports triple-channel memory.    But if you install them as I've noted you'll still get dual-channel operation.

The SATA connections don't really matter, with two exceptions:   (1) If you're using one of the RAID controllers you obviously have to connect all drives for that array to the appropriate connections for that RAID controller;  and (2) if you have a SATA-6GB drive and want it to operate at the 6GB speed you have to connect it to one of your two SATA-6GB ports.

Your hard drive is in fact connected to a 6GB port -- the two ports on that connector (GSATA3-6 and GSATA6-7) are the two 6GB ports.    All of the other SATA ports are SATA2 (3GB) ports.    These are shown fairly clearly on page 7 of your manual [http://download.gigabyte.us/FileList/Manual/mb_manual_ga-x58a-ud3r_v2.0_e.pdf ]
