Pauls Himalayan Musk is huge - much too big for a colonnade unless you live in a stately home, and even then it'd be better growing into a large tree - it'd fill your garden!
Have a look on this site http://www.classicroses.co.uk/products/roses/kathleen/ - I think Kathleen would look lovely on a colonnade, but there's a really good search facility down the left hand side of the site - you can spend many happy hours putting your requirements into it and seeing what it comes up with - and don't panic, this is the time of year for planning, not doing
And to be honest, I'd give Generous Gardener a little longer before moving it - a rose bush can take a year or two to get it's roots settled before it gets around to really performing well. A handful of Fish Blood and Bone around the roots next month will perk it up no end
And congratulations on your baby - what variety did you get?
