Sounds like you are already on location and can't go back and get the hardware you meant to bring.
No worries, this is not a disaster. It might even be a good thing.
Personally, I usually
hate using lavalier mics on talent, and will almost always boom with a shotgun mic, even for things like sit-down interview setups. We usually use the Sennheiser MKH416, but the Rode should serve fine. A boomed conversation just sounds so much more natural and open than when the talent is
wearing the mic, which although might sound clean is still very cold and sterile.
If this is an interior (which I'm guessing, since you are worried about room echo), don't worry about the blimp or the dead cat... unless you are expecting a lot of
wind indoors. :) Just use the mic on the pole naked.
Maybe use the blimp only if the operator is going to have to swish the mic around a lot, but the fur windjammer is definitely not needed indoors.
If you can, you can position your talent to eliminate some acoustic reflections... keep them away from big windows or other hard surfaces, or blank walls, or exactly in a corner the same distance from two converging walls. If there are a lot of hard surfaces in the room (hard uncovered floors, blank walls), sound blankets can be your friend... put them on floors, hang them on out-of-frame C-stands, things like that. If you didn't bring any with you, any moving-supply store usually has furniture pads for rent for just a couple bucks a day which will do exactly the same thing.
Have your boom operator mic smartly... the Rode should not be pointed right at the talent's face, but rather just below their head... at about the base of the neck.
I don't think this is a crisis... you might wind up with sound you like
better.
