I'm not sure what to tell you since I haven't gone through it, sorry - I entered on a fiancee visa. However, unless you get a company to sponsor you, you won't be able to work until you get your FLR. SOmetimes you can get a NAtional Insurance number (temp one) while you're job hunting, but that seems to be on an individual basis. I know my local office said they wouldn't let me, and I had to get a job before they'd even consider me for a number (my interview is next Tuesday, I started my job 2 weeks ago). Someone here will surely be able to help you about your visa though, as I know there are several people here who did the same thing you're doing. Good lukc, and sorry I wasn't more help. :-/
