we had a baby gym which was a good buy. It was a fisher price rainforest theme square mat with two cross bars which arced across the top from which toys could hung. It also had some flashing lights and played music. I think it was about £60 new (it was a present from work) and DD loved it from about 2 months onwards. Her and the dog would lie under the toys and she would have a good kick around, look at the animals and lights etc. She never complained when she was under it.
We also got a bouncy chair, again fisher price. It vibrated but we never used that feature. We used it pretty much all the time from the day we brought her home. It also had a cross bar on it from which toys hung which she could pull and make them play music. She would randomly hit the toys occasionally until she was about 4 months i think and had enough motor control to actually grasp them. It was a very handy place to put her when i needed her to be occupied and safe, like when i was having a shower etc.
Both the baby gym and the bouncy chair can be picked up quite cheaply on Ebay now, even BNWT.
I do wish we had invested in one of those big padded play mats as it would have been handy to take into the garden on nice days. I will be getting on for DD2 (who is also due in May).
We also got a nursing chair quite cheaply from kiddicare (great retailer by the way, cheap and fantastic service). To be honest while we use the chair loads for DD1 i do wish we hadn't bothered getting a specific "nursing chair" cause it was rubbish for breastfeeding (arms were too high and was always running the risk of crashing DD1's head into them). I think the Poang chair would have been a better buy but didn't think of it at the time.
We borrowed a friends moses basket but DD was out of it by 9 weeks and sleeping in her own cot in her own room. She was a very long baby and would whack the sides and wake herself up. If you cant borrow a moses basket you can pick them up very cheaply either on Ebay or at something like an NCT nearly new sale. Alternatively if the pram you buy has a solid carricot open you could potentially use that.
As to prams/buggies/travel systems, it really is horses for courses. It entirely depends on your lifestyle, where you live and what you intend to do with the buggy. I had a brief love affair with the icandy peach but in the end fell out of love with it when i realised that DD1 would be really squished in it when the second seat was added. When she was born we bought a Phil and Teds Sport with a view to adding a second seat when and if No2 came along. No2 is now brewing and i am trading the sport in on a Baby Jogger City Select as it will meet my needs better. You would probably benefit from having a look through the pushchair section on here to get a feel for your options.
God, i have written an essay. Apologies. I have a bad case of "i want to be on maternity leave already" and am trying to avoid actually doing any real work 
Hope it helps anyway.
