allthough I am a longtime professional photographer, I have hardly ever worked with Lightroom, since I do evrything with Bridge and PS.  
Since I have started using LRT 4.7 Pro a week ago, I am force to quickly learn the Lightroom workflow. Offcourse I can go to a standard LR tutorial on the web, but maybe one of you guys can tell me if there is a better way to get the learning curce as closely related to LRT as possible, so I don't waste hours with info I don't need and can focus on what I do need to learn from LR.

Any good advice from you guys, please?

If you are used to Adobe Camera RAW from Photoshop, the Lightroom Develop module should be really straight forward for you.
I'd suggest to follow my instructions on http://lrtimelapse.com/workflow - 2nd tab "visual workflow" - the ightroom part is just for editing the keyframes and that's basically the same like editing in Camera RAW.
