Many amps put out more than that, so to avoid too much stress on the amp, and keep you in the smaller signal region, it might be wise to not attenuate the signal TOO much, the approx. ten to one attenuation I recommend works fine for most typical 60W and up amps, but for a low power tube amp, it should be attenuated less.
You also need to match the transformer load requirements a little closer than for SS amps.
I would try 40-50 ohms and then a 10 ohm shunt, and use the 16 ohm tap (assuming you have a 16 ohm tap). Yes, 2W should do it for the power dissipation, but 5 or 10W will reduce any thermal modulation of the resistance, as well as reduce stress. At these power levels, why not use more margin, the resistors do not get that big.
