Unless you've got a lift, a good set of Craftsmans, and know your way around a garage in the dark, I would recommend you take it to a shop and have the springs professionally done. It'll take about 2-3 hours, depending on how expert the shop is.

As to how low you can, I'm not really familiar with the stock spring rates for the E60, but if you just swap about the springs without getting new shocks, you'll get premature wear on your suspension system, run negative camber (meaning you'll wear out your expensive 20 tires prematurely with uneven wear), and maybe even some rubbing.

Without knowing the exact numbers, I'm guessing you can drop less than 1 inch without much problems if you get an alignment soon thereafter.
