Don't ditch the charcoal canister, if anything replace it with a smaller one from a newer vehicle. It gives the gas that would other evaporate out of your tank somewhere to go until it can be used by the engine.

As for the EGR removal, if you're doing for looks, fine. But it also helps reduce your combustion temps and has been proven on the dyno to make no noticeable performance difference whatsoever.

where is that located at?

The bvsv is part of the charcoal canister's system (evaporative emmissions control). You don't need to remove that or the charcoal canister unless you like gasoline vapor in you engine bay or just evaporating out of your tank. Dunno about you, but i'm dead set on burning every 10th of a cent worth of gas I buy these days... a few years ago I may have felt differently.

It is on the thermostat housing it has two vacuum fittings coming off of it

I got a 1989 Supra because my friend wouldn't pay me back. It had a blown head gasket when he got it. He did that work himself, I'm a little worried about that, haha. But he also did the egr/canister delete.. As well as he got rid of the 25719 tank "vacuum surge" with maybe a few other things.. I don't know if those can be taken out or not? And if not, will that stop the car from running/starting?

7mgte removal of charcoal canister and EGR

Now remove the vacuum hoses that are highlighted in red. And cap off the vacuum ports that I highlighted in green. That’s all there is to it for a stock setup.

as for the blocking off i was reading a little more on this, if i got this right the right red circle you want blocked off. but as for the right one you dont want to block off, the 2nd block off goes onto the intake plenum heres a pic of that

Same thing as before. Red are the vacuum lines you can remove and the green is the places to cap. And the blue dots are pieces that you can remove.

"NOTE"
i got all this information from other peoples post, so dont try to think im smart :)

Sounds like a bunch of people have no idea how the EGR works or what it actually does. :dunno:

Cre is correct, it serves a valid purpose and does not adversely effect performance in any meaningful way. Unless of course you're relying on the data from your ass dyno.
