Where would you choose to go, and what would you choose to take? (Note, the TTC immunise you against any diseases you might meet, and cure any infectious ones you might take. They also cure permanent disabilities such as diabetes, so you won't have to worry about insulin. Broken bones etc, however, you're on your own.)
The enforcement agents are rather regretful, and will provide you with stuff you haven't got, as long as you clearly state what it is, and it's not too inaccessible or unwieldy. Your arrival will create another timeline, so you don't have to worry about destroying your own past.
