Yeah 8 sounds about right, you can only get about 16-20 bonus tokens a season.
As far as your roll is concerned, yeah you could have done better but I've seen much worse so it's not the end of the world. I would put all your points in speed and train agility/vison on intense. Keep putting points in speed until you get to 68 (3rd cap), then switch to agility.
Or if you wanted a more balanced build and LB that will have more of an impact early on in his career, then only get speed to 60 and focus on getting agility to 60.
In both cases remember to put all your equipment in speed and hopefully you will get a decent AE piece as well, oh and never boost till the end of the season until you hit levels 22-25ish.
