Ideally these questions should have been posed in a different forum, not the adult forum. But let's assume that you are pricipally looking for the adult channels and give you the benefit of the doubt...
All channel info (what is where, which satellite, encryption system, etc) is available at several sites, the best of which are lyngsat & satcodx. Check out the links section of this "satellites uk" site.
They also show you the footprints of the various beams carrying the signals, and give an indication of the signal strength at a particular location. Using conversion tables it is then possiblke to get an idea of the size of dish you need.
Please use the "search" function on this board to locate more info on this. I've posted lots of links to such conversion tables and footprint info in the past.
You can usually distinguish between a card that is programmed correctly but with incorrect (out-of-date) keys, and a card that is not programmed correctly (or which has been programmed with bad softwarte). In the case of a key-only problem, the card will be recognised as (eg) an Irdeto card, but a message will be displayed to the effect that you have no rights to access the program (exact message depends of course on the actual receiver, the CAM, the firmware version, etc.)
In the case of a badly programmed card, usually the card will not be recognised at all. A messaage like "please check your card" or "an error occurred with your card" should result.
Note also that most software for programming cards comes with a verify function. This will read back from the card what it has just tried to write - and if there is a difference, the verify fails.
