G1000, great choice.
Use your right hand to manipulate everything Garmin, it's all there so right hand makes sense.
nkand offers good advice... and here's a little more detail that'll put your approach in good stead.
Intercepting your approach profile, lower the nose and back off that power just enough to keep your speed from tipping 120KTS. Should give you a nice approach all the way to 500' above MDA/DA. Reduce to 1500RPM. Should slow to Flap speeds with plenty of room to spare.
I will re-affirm muffman when he said...
Glass is a very efficient weapon in the hands of a poorly trained user.
...and will add that it is also an unparalleled tool in IFR if used to it's capacity.
Have fun.
