The wavelength of 10MHz in air is about 30 meters, so you shouldn't need to worry about impedance matching except when driving an antenna (for optimum power transfer) or long transmission lines (like 3 meters or more). In my experience, Smith charts are mostly useful for looking at port impedances, return loss, etc., so the same thing is true.
As your prof said, pay fairly close attention to layout, including planes, crosstalk, supply decoupling, etc.
For a bandpass filter, you will have to consider stray and device capacitance if you want the design to be predictable.
