cool that ur getting ur bow friday bear's are good bows i am getting my next bow probaly over the summer and i am going with a bear, but anyways the whisker bisciut is a great HUNTING rest, sights i like truglo but trohpy ridge makes good sights and so does cobra, but my preference is truglo good and cheap, i think any stabilizer will work so yes the doinker will work fine the true glo quivers are also good quivers, arrows i shoot easton st epics quality arrows at a fair price (i am on a budget) but if you are going to shoot a bisciut which i recommend by the way you should have blazer vanes on your arrows they never wrinkle and are tough, and i know you didnt mention this but for broadheads i would go with muzzy's.
by the way i would also go with a 3 pin sight, and the truth is a very good higher end bow and have fun and good luck
