Fitting coilovers, what components to refresh at same time?

[pothole]

Am plotting a coilover based suspension project soon. While I'm in there changing the shocks and springs what other parts does it really make sense to change.

I've already got top mounts all round on the list.

Please bear in mind my budget is limited. So I'm looking for things that fall into the crazy-not-to category rather than that-would-be-nice.

Thanks
