Scottie ... with regard to the bus - have a look here wroclaw.jakdojade.pl/?locale=en.
Enter under A "przyst. PORT LOTNICZY" and under B "przyst. Renoma". From there you can easily walk to the city centre. You will see that it costs PLN 2,40.
With regard to the taxi - since Sunday March 11th the new airport is open. So the distance is a little longer. Nowadays there are only three companies who are allowed to carry passengers from the airport. The fare should set you back around PLN 50-60.
If you want to go for a beer, don't hesitate to send me a PM ;)
