please give me advice :)

Im putting up my trax dish with h-h motor im I right in believing all the sly dishes on my street (pointing the same way) are pointing south ?

I also have a dream box d500-s how do I put my cline on to it after purchase?

And is there any tips or pointers you can or want to give me on putting up my motorised dish and installing the dream box.
