Neither are expensive and you should be ok to reuse them when you get your BMWP springs.

- the bolts for the lower shock mounting (2 per side and kind of pricey for a torx bolt)

For the upper mounts, Monroe makes a hard rubber product that is inexpensive and a bit of an upgrade from the foam-like OE ones. (I'm assuming you're are NOT on runflats).

I don't know if the B4 has internal bumpstops. If not, you will almost certainly need new bumpstops unless they were replaced recently. They tend to degrade to the point of crumbling.
