if you want an iPad I say get one now no point in waiting for a new refresh.
As for the macbook depends what you want a macbook pro or macbook air supposedly they are making a 12" mba but I have no idea when they will release it some say 2015
As far as the iPad is concerned, hang tight until Oct 21 when there is a rumored event. There are no further expected upgrades to the MBA or MBP lines this fall, but since you're not in a hurry, why not wait a couple of weeks.
As noted by T'hain Esh Kelch, if you don't follow the MR articles regularly, the Buyer's Guide at the top of every MR page is your best friend.
