How to get through top design house in UK?

Hi frndz,

I am an Indian Graphic Designer packing my bags for UK sometime in mid 2005. I have done my B.F.A (Applied Art) from Delhi College of Art, INDIA. Well versed with all the softwares i.e Adobe Illustrator, Adobe Photoshop, Adobe PageMaker, Corel draw, Quarkxpress i have both PC and macintosh skills. I am learning web design these days (HTML, Dreamweaver, java script and Flash).
Have worked with an Top Advertising Agency in NEW DELHI,INDIA for 1 and a half year. Presently i m am a freelancer designing for corporate clients independently from last 8-9 months.

It will be gr8 if all of u out there could help me with my queries/doubts

Will my Indian education n experience help me get a decent job in a top design firm in UK (London) ?

Though i m updating my resume, buliding my portfolio online, working on my skills, what else can i do to prepare myself for that competitive enviornment ?

I have a worked with an advertising agency but as a freelancer i m handling mostly Design oriented work i.e branding, brochure designs, packaging etc , as i m more keen into design n want to pursue a career in design than advertising. Will this switchover be easy for me in UK?

Also really keen into webdesign, though i m learning it as of nw…how can i get some freelance webdesign work in Uk once i m gud at it ?

Kindly advice , it will be a gr8 help, also gimme some additional tips as how can i be more prepared to hunt a job in UK. How can i contact them? Does the design world there follows different ways for interviews, portofolio submissions etc etc
