Everything I have found and read, tells me the trim pots are supposed to point to the rear of the board, away from the power headers..
I have a similar problem too, but mine reboots the lcd over and over whenever I have more than 1 driver installed, and causes the arduino to get hot on the transistor right below the 11A power header on the ramps board. But arduino doesn't heat up with no drivers installed on the ramps 1.4

It just through me off when it worked correctly when I connect the z axis stepper
to the y axis controller and it moved properly.

2267 was what I set the z axis to with a maximum feed rate of 20.

Next biggest issue is no voltage coming from the extruder.

Any thoughts on that?

I've tried messing with the thermistor since I read in a forum that it could effect the exturder from drawing voltage but nothing seems to draw voltage out

that made no difference.

Still moves 3 or 5mm at a time no matter what I put in for the steps per mm

it does speed up when I increase the steps per mm but it doesn't move more then the 3 to 5mm no matter what.

with the pins making full contact.

There's still a little piece left that I may have to get with a dremel since my snips aren't strong enough,
it appears it's making full contact so I don't think it's the case

Maybe you can slightly bend the pins to get the Z connector in place?  I don't suppose the increased 8825 driver height is having an impact?

I believe I purchased this one

http://www.ebay.com/itm/RAMPS-1-4-PCB-F … 4ac5931b89

Mine is blue

Not sure if this is the one I purchased since ebay seemed to have deleted my purchase history just for this item.

Weird...

The only connectors I replaced were the endstops, and extruder driver fan [connected that to E1]).  Everything else was fine (though a tight fit for the thermistors and LED).

I ordered a new ramps board to verify.

What did you do about the double headers for the z?

Replace the stepper motor connector?

The connector that comes with the stepper isn't capable of going down all the way
with the additional pins in front at least not mine.

Here's the thread on that: http://www.soliforum.com/topic/3600/y-stepper-crawling/

In short, I narrowed things down by:

I swapped drivers (the driver is fine).
I swapped stepper wires (the wires/motors are fine).
I swapped PINS on the ATMega (PINS are fine)
I swapped the resistor, and capacitor (those are fine).
