A/C is fairly straightforward, get it de-gassed, remove the condenser and all the alu pipes that run to it from the firewall. Cut the belt and remove compressor. If you can be bothered you can remove the bits from under the dash but if all you want is to make it tidier I wouldn't bother, it's more hassle than it's worth. PAS will be a bit more involved as ideally you should be modifying the steering rack, there are plenty threads about this on the forum.
