why not just transfer in downtown east orange or newark? those areas are all fine, i have a friendn who lives right by the stop in downtown irange.
the alternative is taking train to south orange and take the 31 bus to the hospital.
placenj.com is a site that has some info, and i think they have a bus stop map on the transportation page, since it isn't an NJT bus
do not check their website,
Coach USA the fares are wrong, and timing is wrong, from my experience.
