Invacom QPH-031 install questions.

Just ordered a bunch of new equipment, and want to make sure I am going about this the right way. Here is my setup:
FortecStar 80cm Dish
Invacom QPH-031
SG2100 Motor
Twinhan 102G with MyTheatre 3.38 as my DVB software.

So let me outline the install procedure I plan to take. Calculate and set the motor elevation for my Long(120.7365) and Lat.(37.5846). I came up with 37.58 deg using this calculator(hxxp://satcalculator.freehostia.com). Set the elevation for the dish, which I came up with as 24.03 using the previous calculator. Get it aimed at True South, which acording to my calculations, is a compass reading of 165.75, taking into account the magnetic declanation for my area.

Hook up the QPH-031 to the Diseqc switch(Port 1 for Circular, and Port 2 for linear). From Diseqc to motor, and from motor to 102G. Go into mytheatre, and point it to the most southerly sat(which is Echo 9, 121W). From here, I am a bit confused. I believe I need to make sure it is tracking the belt correctly though, and to do that I need to try to hit the most easterly bird I can? How do I know which is the most easterly bird I can hit? Anyways, If it is tracking the belt correctly, I am golden, if not, I don't really know what steps to take next.

Oh yeah, and before I forget, in the software, I need to set up my sats individually I assume, and on the linear Sats, I will set it to Diseqc port 2, and have an LOF setting of 10750(can't remember off the top of my head)? And for the circular sats, I need to set it to diseqc port 1 with an LOF 12350(again, can't remember off the top of my head).

If you could guys could go over that, I would be especially greatful. Especialy for anyone that has set up a motor using MyTheatre before. Their input would be most helpful, but any input is greatly appreciated.

One last thing, I downloaded some software for sat aiming, the name escapes me, but I will update this thread tomorrow with the name. Anyways, It gives you azimuth and elevation angles for every sat, as well as has a built in sun azimuth charter. You enter long and lat, and it will give you a list of all the sats, with the azimuth and elevation angles for your location, and in another tab, you enter your time zone, and it will give you in 1 minute intervals, the azimuth of the sun from your position. I am thinking of using this to aim my dish. Just hang a weighted string from the center of LNB holder, and line up the shadow of the string with main mounting mast at the time of day when the sun is at 180 degrees)Or closest to it). That should have me aiming at due south, unless I am mistaken. Anyways, what do you think of this aiming method?
