1 the whole caster role has access to. 2 is a 2 minute combat utility which, fair. 3 will bankrupt you so hard you might as well be dead if you abuse it (read, use more than once per minute).

Now as far as BLM damage vs RDM, yes, raise and embo are calculated in. BLM is the strongest caster / dps because it brings no damage utility while Red Mage does. BLM is generally considered less mobile too, but basically it's as mobile as it needs to be. Neither caster likes having to move without preparation.
RDM has more freedom to be mobile, while BLM mobility is more likely to cause a DPS loss and has much longer periods of not being able to insta-cast things. One of their primary combat spells also has a longer cast time than the GCD (Fire IV).
