I've got one sitting in front of me marked "cisco confidential". That's
the one I tend to use as my reference. I've found it to be more often
right than wrong.
If you've got a few box specific questions - I can certainly research
them for you.

Very true,
You must consider how the line cards connect to the backplane. I think that BW can very based on individual line cards. For example, if you go with the WS-X4548-GB-RJ45, then Cisco will only give you a single Gig per 8 ports. So that should give you a max of 6 Gbps per blade. I have never been able to find these numbers for the 3750's.
The problem with the connection based on the Sup is that you often see conflicting information:
I have link here shows the connection to the backplane will vary with respect to the chassis and supervisor
This my summary of the 4507R and 4510R:
4507R
4 GBPS for Sup II+, SUP III and Sup IV
8 GBPS for Sup V
4510R
8 Gbps Sup V
20 Gbps Sup V-10GE
Who really knows what to believe?

I should also note that I've seen conflicting information on that 12
Gbps number being a Full Duplex number and a Half Duplex number (I have
2 docs in front of me that are conflicting).

If you're going to state numbers, lets talk about the REAL numbers ...
each card only has access to 12 Gbps (6 Gbps Full Duplex) to the
backplane. This applies to a: Sup IV, V or V-10GE.
