My question is, apart from the awesome Amanita Design games, has Floex made anything else? iTunes gives me Pocustone and a remix. Is this the same Floex? If so, I'll definitely give it a try.
Yes, Pocustone and that remix you mentioned are both Floex's. We've discussed Tomas' music and contributions to Amanita projects in a couple of threads here on Machinarioforum and you can find them using the search feature on the forum's main page. Meanwhile, one website you might enjoy visiting is this one:

As for those those Czech translations hopefully someone else can provide them for you.
