Re the props yes the 11x 4 is the way to go. Grey Graupner props are the most resistant to damage but Masters are almost as good. Avoid APC props as they are brittle.
I would not be surprised to find the transmitter in your friends house somewhere. If not a suitable used transmitter should be easy to find. Your instructor at the club you join should be able to help you find one. There are a couple of 'gotchas' on channels he can help you avoid.
Get new transmitter and receiver batteries.
Futaba transmitter receiver batteries come with a charger universally known as a 'walwart' This is all you need to begin with. Again there are lots of these around. Charge overnight before you fly. Something I recommend is the use of a simple programmable light timer eg
http://www.walmart.com/ip/CJ-Tech-60...Timer/48660160 set it to charge for 1 hour every day. When you come in from flying charge overnight then leave the charger plugged into the timer so it gets a 1 hour top up every day. That way when you go flying your batteries are always topped up.
It is a nice looking plane and should fly well. Tell us how you get along.
