Relocation Info on Barcelona

Hello Everyone! Me n hubby are looking to relocate to Barcelona in the near future. I am currently job hunting, any additional info on jobs openings for native german / english speakers is much appreciated! I am also interested in general info on how to find a flat in BCN, as well as to what is required in order to officially work there as a EEA citizen (as well as Non EEA, as my hubby is South African), i.e. National Insurance Number, Health Insurance, etc. Any info is of help at this stage, so thanks to everyone in advance who is willing to share their knowledge! Greetings from rainy Wales!
