Before you spend any more money you need to check which spotbeams the channels you want are in a spotbeam where you are.
=====
If the channel you want are on Ku-band:
Your LNBF's are probably not going to work reliably

check the pictures and you'll see that the LNB you have performed poorly
Also all of your choices are really weak for northern states (I assume your location is New Jersey) and for dishes you'll need 4 footers (which will cost a pretty penny on shipping) for what little is on 113W and 116.8W on the Ku-band.
=====
If what your wanting is on C-band:
"Bad": You'll need a motorized 6-footer (or multiple stationary dishes) or larger
Good: 113W and 116.8W are high power c-band satellites and are easy to get what channels are available up in the North American spotbeams. I haven't seen 45W so I have no idea.

I'm partial to fixed dishes especially with dual-tuner/recorders units that you have.
3x cband dishes (6-foot, preferably 8 footers)
3x dual output C-band LNB (or bandstacked)
and someswitches and multiswitches but that's the harder part figuring out the cheapest method.
