New 996.1 C4 owner - tons of questions

I just bought my first 911 in what was probably too rushed a decision (after a lifetime of rumination). It's a 2001 C4 and so far all the major stuff seems in order - low miles, IMS retrofit, RMS and clutch done, no plastic in the oil filter. Here's what's on my list: Next steps: I assume I should change all the fluids since the car is new to me. Besides oil, is there a diff I need to check? I don't know anything about AWD on the 996. How does it split power, anyways? Wheels: I need new tires and am wondering if I should update the wheels at the same time for something larger (and lightweight, and affordable) than the 17 twists. Recommendations for wheels? Tire wise I'd probably get Michelin A/s 3 plus unless someone has a better recommendation for the wet. Brakes: Brake pedal feels firm but stopping power is lackluster and hard to read. Distance is too long. Thinking of starting with rotors and pads if I can use cheap aftermarket parts. Any complications to the job (eg gratuitous use of sensors and whatnot)? Parts recommendations? Electrical: Probably time for a new battery. Interstate from Costco or....? Is the battery under the trim next to the frunk? I have a Becker CDR 220. Is this still the best option to add bluetooth? https://www.discountcarstereo.com/a2d-bkr.html Can I tap a fuse to hardwire my radar detector or will that cause something fragile to break? My reverse lights are incredibly dim - I can't see where I'm backing up at night. Recommendations here? LED bulbs? Trim: This has the older side-by-side cup holders that push out, like so: https://www.ebay.com/itm/VERY-NICE-U...4AAOSw2ipfBflg One of them refuses to close. Anyway to repair, or do I have to replace? Can I replace the CD holders with something more practical? Ashtray (or whatever it is) in the center console refuses to close. I found a small plastic spring that had been discarded. Repair or replace? Parking brake lever is pretty worn - cheap replacements anywhere? Driver side sunvisor mirror is missing the fold down cover - the mirror is in my face when I pull down the visor and sometimes reflects light. Do I have to replace the whole visor or can I find this part specifically? Roof: I have the stock rails. I have a carbon fiber bike, which Suncoast tells me is not recommended with the Porsche bike holder. Recommendations for aftermarket bike holder? Recommendations for a wind deflector to use with the sunroof and above rack? PS: When do I start worrying about timing chain guides? Currently at 42k miles. Thanks in advance for all of your help. I sold my last German car over 10 years ago and I forgot about what makes them special and what makes them frustrating. I swore I'd never buy another one unless it was a Porsche - so far it's worth it; had a lovely drive over the mountains on the same road Porsche used for a Cayenne press junket recently https://www.gearpatrol.com/cars/a616...nar-landscape/

I can't comment on many of the more substantial questions - as I am also a new 2000 C4 owner. Of course, I read a lot of info *after* making the purchase, which is how i find myself owning a brick at the moment - but I'm working on that There is a TON of info online. Where we share common cause: * Ashtray also doesn't close. I saw a DIY project someone put a homelink garage opener in that space. i have several mini computers (rasberry pi, jetson nano) I was thinking of wiring in. * parking break lever is also worn, but mine is of the Walnut Burr Dark variety, so its probably insane $$ to fix. The door pocket lids were $700 each. * also have the rails and a bike (not all CF), but i haven't looked into a holder for it yet.
