TTW adds edited FO3 masters to your FNV install, otherwise you wouldn't be able to play in DC through the TTW mod. If you're only seeing 2 other FO3 .esm files, then you need to be sure you have all the DLCs for FO3 and FNV...
Here's my .ESM load order:
- Stuffs:
FalloutNV.ESM
DeadMoney.ESM
HonestHearts.ESM
OldWorldBlues.ESM
LonesomeRoad.ESM
GunRunnersArsenal.ESM
CaravanPack.ESM
ClassicPack.ESM
MercenaryPack.ESM
TribalPack.ESM
Fallout3.ESM
Anchorage.ESM
The Pitt.ESM
BrokenSteel.ESM
PointLookout.ESM
Zeta.ESM
TaleOfTwoWastelands.ESM
-All other ESPs sorted by BOSS etc-
If you don't have all the masters I listed, then you're missing things that you need for TTW to function...
