yes, having the licence does help. it would help if you had moto ins. get a scooter - it's like 2-300 per year and it'll help in 2 years when you get your 'real' bike.
at 6'6 you'll have a hard time fitting on most modern SS bikes comfortably - remember, they're getting smaller and smaller! if you don't fall into the 80% of ppl thinking SS bikes are the best thing since sliced bread, there are tons of nice bikes that'll fit you nicely.
