Because you are level 14, the OP and his drivers are all level 19. The stars are a visualisation of the level difference between the staff/driver and your manager level.

It doesn't appear to have any detrimental effect on their speed. A few months ago they used to max out at L18 / 4.5 stars when they had 20 in all attributes. Jack fixed this but the drivers didn't appear to get any faster.
IMO, with staff the stars are important but drivers the numbers in the attributes are what counts.
Yes, the only effect is that it's possible to train drivers a tiny bit faster because they are always of a slightly lower level than expected. For drivers only their stats matter, which is good because who would want drivers that suddenly get slower every time you level up? Getting level 19+ would be the most dreaded event in the game then. ;-)
