Common tools are fine if used with care.
Removal: Straight blade screwdriver with a fat blade. The more blunt, the better. Use a rubber mallet (the light one's, not the pellet filled type) and gently tap the cups out from the inside.
Install: Couple ways 1) robber mallet and section of wood. Again lightly tap so that it gets seated straight. Or. 2) section of allthread with two large washers, enough smaller washers that fit inside the cups, and two nuts. The washers will press against the cups and the nuts seat the whole affair.
Aside from this, take it to the local LBS and they may (if you have an inside line) install it for free.
