So my 10 bolt has been making a whole lot of noise so i decided to change the oil in it, with the hope that it would quite down a bit. The oil itself didnt seem to be too bad, but there were shaving in it. And alot on the cover itself. Is it time to replace the rear or maybe rebuild it?
Everything that is visible in the pictures looks fine. Nothing unusual in the gear wear pattern. Those are not 'shavings' on the magnet,it is iron/steel wear dust held in the magnetic force lines of the magnet. What's on the magnet looks fine.
What can't be seen are the pinion bearings,carrier bearings,and axle bearings. And changing the fluid will increase the longevity of those that are still serviceable. What's on the magnet is also in the fluid you drained and that fluid was a slurry of abrasive iron/steel dust that plays hell with bearings.
What kind of noise was it making ?

Like a howling type noise but very loud. And it louder if im turning one way versus the other. But even when im going straighy its very loud. I drove it just now after changingthe fluid and i dont think it got any less noisy.

Noise increasing while turning is an indication of a bad wheel bearing. If the noise increases while turning left that means the right wheel bearing is bad and vice versa.

Should I replace both just to be safe? And are there better ones then the one that came from the factory?
If axle bearings are gone/worn/broken,axles could have been affected. axles might need replacement too if they're beyond serviceability. NEVER use 'axle saver bearings'.
The gears look great, Check the pinion bearings for free play, as well as carrier and wheel bearings. If you can rotate the wheel, while in neutral with the help of a buddy and listen for noises. Remember keep you hands out of the gear area, and have it properly on jack stands or a full lift. Bad wheel/carrier bearings will make a howl, pinion bearings will usually make a higher pitched noise only on a drive/coast phase. If your rear end gears are stock they usually don't whine, and if they do it will be over a narrow speed range and be quiet the rest of the time. Also torsen rear ends will make some clanking noise when coasting around a tight turn off the throttle and that is normal for 1999+ f-bodies.

What axles would you suggest? The car is pretty stock right now, but should be getting a cam and headers in a near future.

How would I check the bearing? Just move them around? And its definitely a howling noise.
If it increases in intensity while turning, It is most likely weal bearings especially if you have 100,000+ miles on her. Replace both sides, don't use axle saver bearings! If you see any pitting or gouges in the axles replace it, so you don't chew threw new ones and have to fix it twice. If you bring it to a shop, go to a drive line/diff specialty shop not your average "mechanic" cause these rear ends are picky in how things are set up and installed.
And this is why you do NOT use the axle saver bearings...
This is why I like pictures This was caused mostly because of my stupidity, however this is to also prove a point: don't use the axle saver bearings!!!

Which axles would you recommend to beef up the rear end?
If your keeping a stock carrier, you need to stick with 28 spline axles. If you are at stock power levels OE axles are fine, if you want a little stronger you could upgrade to stronger Yukon axles.

Well right now the car is stock, but its getting headers and a cam soon. So i wanted to beef up the rear while its apart
