A. Yes. A "ton of money" is unspecific and perhaps a little informal but it's OK.
B. No. We don't say "it was invested plenty of money". "Plenty of money was invested in it" would have been fine, the same construction you used in A. It's a slightly uncommon usage of "plenty" but you will hear it used this way.
