So you don't get the dmg either? Because there's no equipment in the PHB...
Can you lobby for SRD instead of PHB? It's readily available to everyone with an internet connection at d20SRD.org, and would help dramatically.
That being said, I would pick Warblade, because with Favored Soul there are too many other books you'd need (CDiv for the class, SpC for the spells, CChamp for OTHER spells). Warblade is pretty contained in a single book.
Can you get homebrew allowed?
Do you know anything about the rest of the party? If you'd like to be both beatstick and party support is to play a bardblade, which still only needs ToB; I'd probably then grab either Dragon Magic for DFI and Silverbrow Human, or Magic Item Compendium.
Even if you don't want to go bardblade, I'd still suggest ToB and MIC.
