I suppose you know that the kit comes with some PE. But, if you want to go crazy (and maybe broke 
) you could order something like this:
http://www.bnamodelworld.com/model-ships-boats-detail-up-parts-mk1-design-md-35024
They're out of stock but you could click the little button on the page to be notified when they'll have it back in stock. They're in Australia but I've ordered from them several times because they've had what I wanted in stock at the time. It takes a bit longer to get the product but it's not too bad.
There's also an Artwox wood deck set for that kit.
I hope others with more knowledge about this kit will chime in with more useful information.
