1) Re paint
As you can see the mesh embbeded in the dish, what is coming off is actually plastic layer(s).
If you are just toying around to see what you can make of it, you might as well leave as is to avoid more stuff coming off.
If you do want to paint it (most auto-paints will do, you will need to carefully clean the dish with a soft sponge and soapy water (dish-washing liquid).
This is to get a base for the paint, otherwise that will come peeling off soon too.
2) Re mount
You have the standard 2.4 Az/El mount, and it looks there is very little rust. Good stuff.
To mount this elsewhere, you need a 6,5" outside-diametere pole embedded into something very solid.
Most people make this concrete, but you will need a very firm base, mening lot of concrete.
This is to ensure the dish don't move (let alone fly away) in stormy weather.
See set-up manuals available on the net for details for a "standard" install.
For tracking the satellite arc, you need a VERY heavy-duty polar mount.
These are generally not available, the only "real" polar-tracking mount are professional types, such as made by apexsat in Germany (
http://www.apexsat.com/motorized-systems/polar-arc/index.htm).
These are very good, but also very expensive.
Alternative is to resort to DIY - but I recommend you get a welding course and an account that the local ironmongers.
If you want to start with sat-dx'ing, get a much smaller dish to start off with (e.g. 100 cm), then you can see if it's something for you.
What sort of sats would you be interested in recieving?
