Best. Instructions. Ever.
...But on a serious note, you may not need to disassemble the dash to get at your rattles. What I've done in previous cars that had rattles here and there (an inevitability on nearly every car, it seems) was to source the rattle and stuff material under the panel/piece that rattled. Felt works great for this job, as does thin craft foam.
The key is that tightening parts isn't necessarily going to eliminate rattles. You'll probably find that your dash is screwed together quite well. The problem is that there is plastic on plastic contact along seams...if these seams are hidden under the dash, then slipping in craft foam of the same color of your dash will usually do the trick.
No matter how much you tighten screws, mother nature will ultimately win. Expansion and contraction of materials due to temperature change, even on a daily cycle, is going to take its toll eventually. Placing some sort of material in between plastic-on-plastic contact spots is probably your best bet.
