Well, I believe there a number of things you need to keep in mind. Firstly which application you are targeting? This will define your specifications. Look back at your specifications!! Then you must decide which methodology you will be following for your filter design. Do you want to make a simple passive filter? Or is it active (op amp and resistors/capacitors), Gm-C type or a switched capacitor (resistors replaced with switches and capacitors in active filters). If you have to make op amp based filters, which transistor technology are you using? BJT, CMOS etc. An excellent reference is chapter 16 of the book "Op amps for everyone" by Texas instruments!!!!! Plz go thru this chapter!
