�30k before tax is OK, but if you're single it will be expensive as there's nobody to share the rent/living expenses with! I would say buy a flat, but if its only for a couple of years, hardly worth it & you would have problems getting a mortgage anyway....
EU driving license no problem, but not sure what happens if you're here for over a year - worth checking DVLA website for foreign nationals driving rules. Also, there maybe implications with insurance....
