Record/radio console project advice/experience

Little background:
I'm moving in about a month, and the new house will have office/retreat space for me (in theory). I love records and have a decent collection, but since marriage and children, I haven't been able to listen as much as I'd like.

Anywho, My mom's giving me her mom's old (inoperable?) record player/radio console. My plan is to gut it and retrofit it. Does anyone here have experience with this? I plan to loop it into my sonos system (currently only 2 One's and a playbar) Also, this is my lowly turntable. What's a reasonable price to spend on a better performance turntable? Since this will also be a piece of furniture, consideration will be given for appearance of the turntable. Any recommendations? Is there a difference in sound quality from a built-in pre-amp vs not?

Also, because I can't look in the console yet, I assume I'll have to get new speakers. Should I just get some off the shelf speakers and set them in the console, or should I buy a speaker kit and install it into the existing space?

Any advice is helpful. Also, if you just feel like effing with me, you're welcome to do that, too. Also, no pics of mom. though dad did die recently, so she's single (but old).
