Some of the above answers are a bit misleading or incomplete. For example, steel wool is a no-no if you're using a water based stain or poly (it causes rust spots), but perfectly acceptable with an oil based stain and poly. Same thing with grain raising--it's important with a waterbased stain, but not with oil based.
Some woods tend to blotch when stained, so they'll need to be finished a bit differently and it could affect the sanding schedule.
Give us a bit more detail and we'll point you in the right direction (I'm much more experienced at making sawdust than I am at keeping reefs--as evidenced from the almost finished stand and the empty ('cept for water) tank!)
