Do all the competing eurovision countries have single charts and if so how did the tunes do on each of their respective national charts? all number 1 or progress likie daz?

They do - have a look here.

do you know the highest position of each of the tunes by country?

Not all, but I know Germany and Greece's entries got to #1 this year. I would imagine Croatia, Bosnia-Herzegovina and FYR Macedonia's entries would have gone fairly high too. Countries like France and Spain's probably didn't trouble the top 20 though.
