I am not an A/C system master, but have read up on them a little when I was shopping for an E30 without A/C...
First of all, your E36 uses R12 refrigerant (pg 640-11 from the Bentley manual), but this unnecessary information. Before anything, take your car to an A/C shop and have them flush your system completely, this should be free because they can resell the refrigerant (If not pay you for it). Then do a leak test with a can of dyed r134a using a conversion kit fromyour local autozone/advanced auto/oreilys/etc. Something like this below.

And then most people recommend replacing the expansion valve as well.

Not sure on the accuracy of this information! But good luck! I got lucky with my E36 being R134a!
I've redone the entire AC system myself after my compressor 'ate itself alive'. The proper way, is to replace everything. The reason for this is because of what you eluded too; the metal shavings. I opted to replace every single line (high and low), the compressor, and the expansion valve.
Once you have all new components you need to add the oil. The amount you add is dependent on how much is in the compressor (or the whole system). There are a few guides on this and HELMS manual has a calculation you must do. For sanity's sake, if you're close, you'll probably be alright. However, full disclosure, I am no HVAC expert.
You can do ALL of the work yourself save for the charging/recharging/evacing.
The rig and r410a would easily exceed the cost of just replacing it. I already have a vacuum pump so omitting that cost.
