That printout will be handy, especially if it's got elevation and skew on it too, manual(s) - if you are doing motorized, Socket Set that has a lock on it so that you won't be dropping sockets all over the place as you look for the right size... a screwdriver on occassion - a drill with a screw driver bit, a drill bit, possibly a tool apron or some other piece of clothing with lots of pockets... electric tape, tar (if you are going on the roof), dielectric grease, sillicone, mini-level (to get plumb) - small is good so that way it's not too awkward, and you can check the bubble both n/s e/w, and nw/es, etc. - you can get em cheap at wal-mart,
printout of the lyngsat main page for your area - so that you can organize satellites either in the receiver or in channel master by east to west or vice versa. Zip ties are handy. Also handy is thin weed wacker tie stuff... you can tie it to the lnb and to any holes in your dish, etc. and use that to help get the lnb lined up just a smidge without actually moving a bolt...
PATIENCE is the biggest tool to have... Also, several hours of sunrise or sunset on a day you don't have to work is helpful... It sucks these days to be on the roof litterally burning your butt off working on this stuff like I just did.
Also, duct tape could come in handy. At the moment, I've got some duct tape in a big ball sitting between the dish's arm and the invacom lnb to hold the lnb in place along with some zip ties and the weed wacker stuff. That quad lnb from invacom is pretty darn heavy and does not like to stay where it should because of gravity...
