You will be waiting a while then since IC is going to be last due to its size.
Get the mod as it is now and install the updates as they come.
For travelers, many use Tamriel Travellers (two l's or one l...spell check/dictionary says one...but the mod is two l's) along with CRR or others.
TT is included in the T.I.E. mod so if you ever get that don't use TT with it.
I am currently using TIE with CRR, Kuertee's http://tesnexus.com/downloads/file.php?id=25449, and Phitt's http://tesnexus.com/downloads/file.php?id=32747.
The latter two are less road encounters, more overland and possible city (kuertee), although I haven't seen much of WE inside cities yet, other than a giant rat dead in Chorrol some NPC killed.
