Forgot to come back onto write - aside from cutting 10 minutes off my commute (seriously - 1hr down to 50m, managed it in 46m recently!) it has been amazing. Changed the stem for a slightly better fit, new bar tape (shiny blue Benotto that certainly goes with the colours on the bike), new tyres (didn't notice a patch of wear in the rear sidewall until it went pop at 30mph, still good fun!), pedals swapped out, new pads and everything all cleaned and lubed. Not much else needed work, at least not yet. Away for work at the moment so haven't got any pics to post.
I definitely understand why people have called it a stiff ride though. Going from a very forgiving steel frame to the CAAD has been interesting for my backside and hands.
Hope your new place is working out!
