So Jonathan CAN still write diary entries, but he no longer can send letters? The things that were stolen were paper and envelopes he had brought with him to write to Mina and his boss during his travel?

Yes! Along with his letter of credit (functionally credit card, so thus his money), his information about trains and such (thus his ability to plan any kind of travel), and basically all of his other loose papers. And his travel clothes.

Jonathan still has his diary, because he always keeps it on his person. He also still has access to writing tools since he's used them to write this entry, just not other paper. It's less clear on this case whether Dracula stole all his pens and whatnot, and he only still can write because he keeps some on his person as well (I can't imagine he doesn't, given the various places/times he writes in his diary) or if the Count left him the ability to write but nothing to write on (a nice taunt but it would still let Jonathan write on other paper he finds outside his own room, so it kinda depends on how safe you think he'd want to play it).

Regardless, Jonathan definitely still can write in his diary. But as far as Dracula is concerned, he's taken away Jonathan's ability to write any sort of letter (or get very far if he tries to leave).
