hi
"I guess the first issue is that I can understand if I have a LCD contrast pot, or the rotary encoder? It seems I don't have both...what I do have has a small circuit board soldered. Thus, the knob whole in the front of the machine next to the LCD should be for the pot contrast or the encoder? Please enlighten!""
You have a rotary encoder.
imageshack.us/photo/my-images/109/b2002.jpg/
black wire goes to GND on Aux-2. the others D63,D40,D42.
Look pic and you can see it.
LCD: I have wired it this way:
LCD-pins 2,15 wired to AUX4 - 5V
LCD-pins 1,3,5,16 wired to AUX4 - GND
LCD-pin 6 to AUX4-32
LCD-pin 4 to AUX4-47
LCD-pin 11 to AUX4-45
LCD-pin 12 to AUX4-43
LCD-pin 13 to AUX4-41
LCD-pin 14 to AUX4-39
with this changes in the pin.h of the marlin software

"The Buzzer in the above drawing. What's the purpose and what are the specs for it?"
Sorry i dont know it atm.
"Also have the following questions. The power supply shows 20A but we have 11A and 5 A in. Is this OK and will it not overload the board ?"
11A + 5A = 16A < 20A = ok
Sorry this simple answer. Take a wire wich is not too thin
(i cut an old power cable to make sure its definitly not
too thin cause i am not expirienced in electronics).
Connect ( 2 times ) from power supply + and - to the ramps
(one pair for the 5A and one pair for the 11A).
Check everything before switching one power supply.
How to assemble the print bed? lochnessi you had this question it seems you figured it out.
Sorry i still haven´t assembled the bed. I will do it next week.
It´s possible to work without the heated bed if you print
only with PLA.
"Are the sides of the machine closed? I have two additional large black panels and can't seem to understand where they could fit?"
Yes the go to the sides. You just have to push it in (no screws).
I dont place them until everything is finished.
Where have others placed the SD reader?
SD card reader (6x2 pins) go to Ramps AUX-3(4x2 pins). 2x2 pins (the most right ones) are unconnected.
look here:

It seems the fan if mounted on the frame like I think I see in some photos, will only be blowing half, as the other part will be against the frame. Is this as it's supposed to be? Or am I missing something.
I am very unlucky with this. Actually i don´t have this fan running.
Ony reason is that i switched from the power supply to a ATX
cause my power supply is damaged and i can connect a better
fan to it easily.
The more important reason is this fan is not very effective if you
need it. The most important work after assembling the printer
is the calibration of the motors. If you do this well the motor-drivers (pololu) will not go too hot and you can maybe (like me)
run the printer without cooling from a fan.
But the problem is how to do the calibration.
It is nessisary to know first that the pololu-motor connection
can just work good in a small area.
- Too low power means the Motor don´t work or stop somtimes
- Too high power means the Motor run hot and switches off
(=emergency stop). Possible that in this case your motor runs
a long time and after going too hot it begins blocking. Very bad !
Best position is a little bid more power than "too low".
I will describe the calibration next week for you.
Time to sleep for me ... now.
