I really wish I had more time to contribute - DP is a complete nappyhead having researched and researched before and since DD arrived. As she was tiny we started with Bimbles (which were gorgeous!) and Sandys which were apparently bomb-proof! We use the mother-ease wraps too I think but they weren't ideal when she was still tiny.
We got most of ours 2nd-hand from a forum called ukparentslounge - some great savings to be had if you do it that way. Also, bear in mind that as they get older, nappy changes are less frequent so we get away with a wash every 3 days now instead of every other day.
For baby monitors, we had a cheap one to start with as were in a 1 bed flat and then made do until this weekend when we finally invested in the now discontinued BT150 as it was on offer in Tescos for £46.66 - not a huge difference between that and the newer version (250) really so seemed worth the saving. We looked at the Angelcare but decided having to faff about with putting a hardboard under baby's mattress for the breathing pad thing was too much hassle :o
For expressing, I used the Medela system which worked fine for me (although I never really enjoyed it tbh) combined with MAM bottles. Probably wouldn't use these again, as although they are good for colic, they are a bit fiddly being in lots of bits. Saw some Dr Browns ones recently that were good.
As for travelling - only you know how you feel, but I would go with the advice to wait until nearer the time. I wanted to go away before baby arrived but was so uncomfortable towards the end that the thought of travelling, staying in an unfamiliar bed, etc no longer appealed! And my first arrived a few days early too - so don't assume anything!
Welcome to all the newbies! Everyone's great here - we're all in this together!! :)
