Do we need it and what does it do? How hard is it to remove?
Firewall insulation

Is this a rhetorical question? Are you referring to the matte in-between the front cabin firewall plates?

With 2800+ posts under your belt, I'm not quite sure how to answer this. But here goes...
The name itself answers it. It serves as "insulation" for both NVH (noise, vibration, harshness) and heat.
As far as removing it, I have no idea and will let others chime in. Although if I were to venture a guess, I would say a lot of engine compenents would need to be removed to gain access to all the mounting/fastener points.
Why, may I ask, are you pondering removing it?

- NVH, as in keeping excessive engine noise/sounds from coming into the passenger compartment, same as the hood blanket.
- It also reduces the heat transfer from engine compartment to the passenger compartment. You have probably noticed perhaps hottest part of the engine (namely exhaust manifold and turbo) is just in front of the firewall. Without the insulation, interior components nearby could melt.

Bloody, furry varmits anyway...
I suppose that's one of the downsides of keeping a stallion in the stable.
It wants to run...
Moth balls did not keep them out for me, but the fabric sheets did.
I had to remove all the under hood insulation and some against the fire wall on the drivers side.
Great PIC!Get a kitten...with a sniper rifle!

Forget the sticky traps, poison, moth balls, bounce drier crap. How large is the poop? If its about the size of a grain of rice you got RATS. The best way to get rid of the bastards is with your standard spring trap loaded with walnuts or pecans. Don't use peanut butter or cheese. Trust me the traps work and work well.
I use to have rats sleeping on my engine covers and since trapping, all is good. Luckily for me I snapped their little necks before any damage was done (just lots of poop on the motors). In total I've nabbed six rats, all big furry bastards.
As for the insulation, not sure how to remove it, sorry. I'll have a look at VIDA when I get home.

tuscani66 is right about more heat soaking through the firewall. It's not just the ambient heat, it's also the radiant heat from the exhaust manifold and turbo. Without the reflective shield, the fire wall will effectively become a giant sponge for heat. Not sure how much you will feel it though, since the climate control will probably deal with it, but I would expect more heat build up under the dash. Bad for electronics IMO.
Edit: Just noticed 'qwkbrk' also mentioned the probability of interior components melting...so he's right too.

I just peeked in my engine compartment and was reminded of this: automotive firewall insulation (blankets) are usually installed at the factories before engine, master brake cylinder, climate control hoses/wires that go through the firewall, etc. There are usually holes cutout for those various components/lines, e.g. water lines for the heater. I also think just ripping it out could happen by pulling, tearing, and cutting; along with the likelihood of a lot of bloody knuckles and cursing. In order to remove the insulation or install it (without damage) you would probably have to disconnect those components and/or remove the engine. Ugh.
Thanks, let me know.

I dug through VIDA but couldn't find anything. It could be buried in there somewhere but I haven't seen it yet, sorry.

I found the part number: 8641898, but no removal or install help.
