Finding my (electric) wheels

Hello, have fitted a TDSZ2 to a Ridgeback Motion hybrid ostensibly for work purposes - horrible U shaped route and too short to make it worth wearing cycle clothing and taking a shower. Have been reading various threads here and elsewhere but have a few queries I cannot find a conclusive answer to;
a) It is worth fitting an extra magnet (or more) for the speed sensor?
b) If so I there any particular spoke magnet it has to be?
c) Mine has a 44 tooth chainwheel and I could do with a smaller chainwheel as well - would a 44 34 or 50 34 combination be appropriate?
d Other than being a 110 chainweel is there anything else that is needed?
e) The hybrid is 7 speed and the chain works okay on the supplied chainwheel - given most chainwheels are described as for more than 7 speeds am I almost certainly going to need to change the chain?

Thanks in advance

Mike
