Manual Transmission whining in neutral?

Thanks for the feedback, folks. I wouldn’t say I’m advanced, exactly, but I understand the concepts, am mechanically inclined, and can follow a good manual (especially one that doesn’t leave out steps that I “ought to know”), so maybe this is worth a shot. I can pull apart a 10,000 hp compressor, so it can’t be too much harder. I suppose the worst that can happen is I screw it up and have to junk the car out, which is about where I am now.

How are the bearings installed in a transmission - shrink fit or anything like that? Do I have to use a rosebud to get them of or a press to get them in or anything specialized? Would I need any special tools or a high quality mic set or something?
