For lower octaves, Shreedage Classic is pretty close and comes with a great amp plugin to boot. If you can throw down some money, Real Strat's probably better if only because higher octaves. Guitars are really hard to emulate with virtual instruments. For amps, Shreedage classic comes with Revalver HpSe(I don't know if IBZ or 2 come with it) and Guitar Rig/Player. If you want to write orchestral music and rock music, I would do orchestral commissions to earn some money and buy the libraries I just mentioned. But I'm not experienced in the field so take what I say with multiple grains of salt.
