I've always done it in two days because I like to take my time and enjoy the views. DEFINITELY take poles. Honestly, an old ski pole will suffice. Depending on the CFS level, you will want something to lean against as you cross the current as well as feel out the terrain ahead of you in the water. For boots, just make sure you've got boots/socks that will dry quickly because towards the end of day one you'll be in water pretty much constantly and you'll want it to dry over night. Last time I went I just took my solomon trail running shoes and they worked great, but, I think it would be wise to use something with plenty of ankle support too.
