Well, two problems, but I'll make two threads to keep things neat.

Problem 1: OK so I bought it a few months ago and it drove fine, then I noticed there was a "clunk" when putting it into first from a full stop. Did research, concluded it was "normal".Fast forward to today, it is very difficult/impossible to put into reverse, and same with first gear. VERY difficult to go into first gear. Also I am hearing a "clunk" coming from the front of the car, even when I'm not switching gears.

Thinking about getting it towed to a shop. Thanks for your time and help.

 

Unrelated to clunk putting into gear. Your current issue is classic clutch drag. Its not fully disengaging.

Shop is going to advise new clutch, even though you probably don't need one. Guessing around $2k. Even if you need a clutch, shop is probably not going to do it all correctly, unless they read up on S specific concerns.

Before you invest in new clutch, there are two things you should do:

1. Bleed fluid
2. Adjust clutch

Fluid any shop can do. Difficult to mess that up.

Adjustment, they'll set it way too loose unless they know how this clutch should be done (which will only make current issue worse). This one is easy though, so if you have a 12mm open end wrench, you can diy.


Also, don't let anyone talk you into clutch 'upgrade'. Stock is going to perform better than anything else you could choose.

 

Your clutch fluid probably ran low.

Bleed it, flush it out completely, fill it, and keep it maintained by swapping it once a year.

Not sure what the other clunk from the front end is. You'll have to diagnose that one.
