Hello. Is glEnable(GL_BLEND) acceptable in OpenGL 3.0 (as in not deprecated)? Or should I do the blending myself, by comparing the FBO depths and mixing the colour values myself?

You can't do blending yourself. Blending-modes are here to stay, not deprecated.

Thanks. I got kinda misleaded by my friend, who claims that GL blending is fixed-function, and modern engines should blend between FBOs or something.

Thanks for claryfing that.
