Dude don't sweat it about the plugins. A lot of people have 'rented' them, it's just a good idea to not say anything and keep quiet about it.
That being said, there are a ton of good plug ins out there that you can buy for cheap or even free that will get you by without having to pirate.
I think with your equipment, you can get great recordings micing your cab. you just have to work with it. I know a lot of us on here record our cabs in small cramped bedrooms and still manage to get workable tones. Just start with one 57, make sure you move the cab away from the wall, and go from there.
