Recaro

I know this has been asked plenty of times but i have no for sure answer for the symptoms i'm having and there's mixed info on these issues.

I have a GSR LSD tranny and when i'm at a stop and put it in first as soon as i barely let go of the clutch even a tiny bit it sounds like a squealing noise almost like a cricket but goes away after letting go of the clutch in first after first i don't hear it anymore it seems like it only does as i'm letting go of the clutch from a complete stop. I don't hear the noise while in idle or as i step on the clutch all the way or even shifting through 2nd-5th. Also the car shakes more than its supposed to when i'm engaging first gear and start moving but all the rest of the gears shift fine, it's just when i take off from first or take off from dead stop for that matter. I just replaced the clutch, pilot bearing and throw out bearing about 6 months ago so i hope its not the ISB or main shaft bearing? Is there even a difference? I'd appreciate any help.
