Medals exchanged for a bonus give you a bonus that works like any other bonus. As the bonus $ are earned the amount earned is subtracted from MGR. (Clear $20 of bonus, lose $20 of MGR, hence lose $5.40 of rake back.)

Medals exchanged for tournament tokens work like entering any tournament. The amount of any overlay is deducted from MGR. (Use $26 token to enter $4000 guaranteed tourney with 100 players, overlay is 4000-24*100 = 1600, overlay per entrant is $16, lose $16 of MGR, hence lose $4.32 of rake back.)
