I agree eBay will become your best friend, I get bulk lots of clothing and sometimes there are things with the tags still on them. A bath isn't necessary, use the sink or hop into the bath with them, they grow too fast so it's only of use for a month.
You want a pram that is easy to push, steer and get through shopping aisles easily. The capsules are about $70 for three months to hire, but good convertible seats can last a long time, just make sure that you can check they will fit in your car.
