Congrats on a 70 point increase! It's onward and upward from here!
You can *probably* get a loan, but it's likely to have a horrificly high interest rate. The longer you can hold out and keep building your credit slowly, the better off you will be. Your CC is only 2 months old; concentrate on charging small amounts (keeping util down) and paying them on time -- always.
Are you talking about opening an additional CC, or two more? It's not really possible to predict the impact on your score without knowing the whole picture. Adding new CCs may hurt in the short term but in the longer view (months/years) may help. Sorry I can't be any more specific.
