Again, I agree with the others on this one.
You'd suit a short control very well, but i would save that extra £30 and go for the 05 version as it looks the business and has an intergrated booster which is a nice extra. :)
However, if you would like to save some money, a T-rex would be fine, personally i don't think you are too small for it. After riding Ross' Toxin for a couple of days i found that extra length did not hinder me much at all, in fact the opposite.
Anyway, the Control forks i believe are 415mm in length. They would work nicely with both frames i think.
As for BBs, I use an FSA one, available from Tartybikes (Although i'm not sure they have them in currently). Its under £30 and still going strong. :P
Cheers,
