You can get a ticker easily, at Lilypie.com, set up a ticker and then use the BB CODE.
Its personal preference when to buy baby things, with me and my partner we have almost everything, mainly people, partners brother just had baby and he passed us his moses basket, etc. Many people say that you shouldnt buy before the 3 month mark because its bad luck , but i beleive this is another old wives tail.
Do what you feel comfortable with.
