LT's advice sounds good to me. I've no 18T experience, but a fair bit of '52 experience.
One thing I'd add is care of that lovely radial engine. You don't just jump in and flick the key, car / PA28 style - this is a real aeroplane and requires a bit of TLC. You'll need to pull it through, and be very aware of the real possibility of hydraulic locks and how to avoid same.
But that requirement of a bit of care is repaid in spades by these wonderful machines. An 18T compared to a PA28 must be like Otis Reading compared to the Black & White minstrels.
