depending on how much previous experience you have
with CPMD and similar packages, it might be worth
doing a few reference calculations with plain DFT
first to be able to asses the computational cost.
as these are going to be very demanding calculations.

if you want B3LYP pseudopotentials, you first have to give yourself a
hand and program b3lyp into one of the pseudopotential generation codes.
at the moment, people simply use the corresponding non-hybrid
pseudopotentials (e.g. blyp).
moreover, you may have to adapt the CPMD code to be able
to handle k-points with screened exchange, which is currently
not available, if i remember correctly.
cheers,
axel.
