You might want to up the MR to Lower Boy Scout Lake this coming winter/spring. This way you can get very good look at the E-Ledges to figure out where to enter and the route. We did this about 5 years ago and still haven't done the MR for a myriad of reasons. My guess it is easier to go get to LBS in this time period than in the summer.
Also, start doing trips off-trail. This will help you with route finding, a skill that is necessary for trips like the MR.
