Hmm, well seeing as how someone helped me with a translation, it's only polite to give you a helping hand
My literal translation of that would be
"A meeting with a friend at a grave. I will show the note"
This is a bit tricky, as there is no tense fro the first verb, and the context is not made clear, however, a real translation would be something like
"I will meet my friend at the grave site, and show him the note"
Though I would be interested what some of the other more fluent members have to say
And the furigana would be ゆうじん と せいざん で まちあわせ。 ノート を みせあう
Pretty much the same as you had
