Three things I am using can help you:

1) Use warning periods together with DEADLINE or SCHEDULED: «You can
specify a different lead time for warnings for a specific deadlines
using the following syntax. Here is an example with a warning period
of 5 days DEADLINE: <2004-02-29 Sun -5d>.»

2) Use http://orgmode.org/org.html#TODO-dependencies

3) http://orgmode.org/worg/org-contrib/org-depend.html
