True, maybe, but think about it this way - if you had installed Windows and had a rare wireless card that needed drivers off a driver disc you didn't have, you would still need an ethernet connection to try and find them from the web; an operating system (or it's installation media) can't usually contain every single possible driver on earth, let alone proprietary drivers that may have restrictions about the use and copying, so it's quite obvious that it's a good idea to have some sort of non-exotic internet connection around at first. But yes, it wouldn't harm if they mentioned it a little better - like "we might not have drivers out of th ebox for all hardware that doesn't have open source drivers".
WPA is WPA everywhere where I know; if the NetworkManager is of any use, it should find out all by itself what encryption you'll be needing. Usually there's only one choice, decided by the access point, and if you have set it up yourself you should know what that is
or if not, you should ask the administrator of that device what encryption it needs.
Third option is always to try, miss, re-try and in the end hopefully succeed..
