Hi, Treble Plink,
Most berths can accommodate fender boards stored under the mattresses, so storing them shouldn't be too difficult, and the lines for handing them will just go alongside the timber portion. I think they're your best bet for protecting the boat from piles, especially if there is a big tidal range.
When you tie up, spring the boat both fore and aft (foreward cleat to aft pile, aft cleat to forward pile, so that the springs keep you located where you want to be on the pile where the board is. You can use a breast line to pull her in, for getting on and off, and if necessary, we've used a kedge anchor
to hold us off. Old timber wharves can have the oddest bits of metal sticking out of them!
If there's a sea ladder, you may want an extra fender by it, as well.
