Hi David

> the positive supply goes to the 7809 with a cap either side between

the positive and gnd and the 7809 grounded on one pin
yes.

> Are the caps anything special i.e. tantalums

For the filtering caps - I do not know how they are called in english.
I'd say: polycarbonat foil capacitors. 35Volt.
