KCDW - have to say 'Don't Know' to all your questions, as I've never used it, as the only times I've ever flown in an area where it would be available, it's been outside published hours and the service provider unit (military) has been closed down.
In theory, it would be a great service, but to be honest, I've got used to talking to the regional information services and find those provide all I've ever needed. Maybe it's just a question of not missing what you've never had!!
PS FFF / SAS - I've got around 190 hrs and have been flying for 8 yrs, have done an IMC course - none of my instructors has ever mentioned LARS!
