I believe Jospeh's dream was before Rachels death. Jacob speaks of '...your mother' (Gen 37.10) I know the 11 stars of v9 would make one think of Joseph's 11 brothers but it could also be 10 brothers and 1 sister.
The events of chap 37 need not have occured after chap 35 as Gen 37 is describing the life of Joseph and could have occured before the events of chap 35.
Rachel dies on the road from Bethel to Bethlehem (35.16-19) 37.3 implies that Joseph was still the youngest as he was the son of Jacobs 'old age' and it was whilst they were still living in Hebron (37.14) that Jacob sent Joseph out to look for his brothers. Jacob was at Hebron when Isaac died (35.27).
