Up New River to Federation

Hi all,
Some mates and I are doing this in just under a month's time and this is us scrounging every last piece of information that we can get! Please let us pick your brains for anything you may know about New River, those of you who have rafted it or walked anywhere near it (eg Salisbury River, Vanishing Falls, Precipitous Bluff, Lake Geeves, Federation Peak etc.).
We're looking for extra info on:
Scrub conditions and what to wear
Variability of water levels
Hints for navigation
Ideas for crossing pools in the river (floating packs, rubber duckies...?)
How to get from lake geeves up federation
Availability of water on Bechervaise Pl
Any info at all would be appreciated. Even the local psychiatrists number for when we get back to Hobart
Cheers
