When aligning the passenger side cam you want it to point in towards the inner dot. As you install the tensioner the timing mark may move a little bit back towards the middle of the dots depending on how much slack you have in the belt. But if you start out with it pointing towards the outer dot then you are guaranteed to be off. It may be part of the difference between aftermarket timing belts and oem (I've been using Gates, which is the same company that makes the oem ones). The cam lock tools aren't really necescary unless you are replacing the cams, cam seals, or cam sprockets.
As far as the trans code, that underlying code is the code that is needed for better diagnosis. The P0700 doesn't really say anything.
I'm hoping that you have just learned the hard way on the aftermarket sensors. Cam and crank sensors especially, they typically are junk right out of the box or don't work for very long. Not sure if there are any aftermarket transmission speed sensors that are ok but I doubt it since they are similar in design.
When it does fire up after a long crank, does it fire up smoothly like it should or is it rough at first and then smooth out?
