You should make use of the dictionary IDs that you created from your CSV:

for filename in os.listdir(path):
    oldname = filename
    newname = IDs[oldname]
    os.rename(path + filename, tmpPath + newname)

But you probably should use some kind of error checking.. (Edit As the other answers have pointed out it's best to use also os.path.join) Maybe something along these lines:

failed = []
for oldname in os.listdir(path):
    try:
        old = os.path.join(path, oldname)
        new = os.path.join(tmpPath, IDs[oldname])
        os.rename(old, new)
    except KeyError, OSError:
        failed.append(oldname)

print failed
