controlling dc motor direction (help a newbie, please)

i have a 1.5-3vdc motor that i would like to turn on and off in
opposite directions using two microswitches. i'm new to electronics,
but from what i've learned so far, i think i want to use a 556 timer
and dpdt relay. striking a switch would turn on the 556 timer for x
seconds (5, i'm thinking), then the dpdt relay, then the motor. am i
right taking this direction?

also, would striking the other switch before the end of the process
cause a problem? i'm hoping that it wouldn't interrupt the motion, and
would like to know if i could have it be ignored by the circuit.

and, testing the motor speed, i've been using resistors to get my 9v
supply down to 1.5 and 3vdc. would i still go that route to control
motor speed, or is there another option?

and help would be appreciated. thanks

david
