I trudge through each build as soon as it is released and beat it to death in as many modules as I can. As far as standard Pro/E goes 2002140 is good, there are many issues with 2001440 and up until 2002140 due to the inclusion of the basic surfacing package. There are many dialog box and redefine issues. I am not currently using Intralink but have seen ghosting and it is annoying, so if it occurs frequently you may want to wait. You may also want to check out the build compatibility of I-link and Pro/E since it may be a problem that is fixed but you have to upgrade to a newer I-link.
