Newb questions about spirits Options

[Abbandon]

I dont have street magic*

#1. "A magician may only summon a spirit that corresponds with his tradition". Does this mean that you just cant summon a fire spirit if your a shaman or a wind spirit if your a hermetic mage? Or does it mean I can only summon a specific type of spirit like Air/wind?

#2. Im pretty unclear on the terminology shamans use and what powers to be calling on. What would I call on for beast spirits??

#3. Should my totem or mentor spirit affect how summoned spirits look or rather can it? I chose to get +2 to air spirits but my totem is bat. There were some cool powers air had like Engulf. I was thinking a swarm of bats would engulf the target if a spirit used that power. Or like if an air/wind spirit used levitate on somebody it might look like a giant bat carrying them? Or would I only be able to make a beast spirit look like a bat. I know you can make them materialize and look however you want but im asking what makes sense.

#4. Oh do spirits have names. If I summon a free spirit and dont bind it and it performs all the services it is owed and goes back to the manaplanes is there any way I can call that specific spirit back later?

#5. Binding spirits looks like a big pain in the butt so what benefit is there besides the fact that they dont disappear every 12 hours?
