Thanks for the replies all, much appreciated.
I've since played around with the saddle, and made it a little more comfortable.
As it all starts to come back to me, I'm concluding that the frame is too long for me. I'm putting too much weight into the handlebars, and getting a it of neck/shoulder tension. Despite my relative long legs, I'm 5ft 10in. Rather than play around with stems, I'd rather have the right frame.
Unfortunately, it looks like I'm going to have to return this great deal.
The good news is that my bug for cycling has come back with a vengeance, and I'm keen to get back on two wheels. Really like this particular model of bike also. Have some more questions, but perhaps its better to start a new thread.
