Finding the hints:
The hint is encoded in base64, decoding this twice gives us the plaintext: stanza, then verse, then word, then letter. This pattern can probably be used to resolve the four-letter codes into letters to form the final word, and it also tells us that these letters will be found in the text of some poem or song. This is further suggested by the music notes scattered in the image, and the final 6-letter word is probably related to music.
Solving the rebus:
I believe the rebus will point us to the song that we need to find the letters. One possible solution for the rebus is (New) + Sea + Land, or New Zealand. With the previous clues in mind, I can think of only the national anthem.
Using the numbers: 1534 2625 3333 2341 5841 4512
Use the English text of the New Zealand national anthem to find the answer.
1534, or stanza 1, line 5, word 3 (triple), letter 4: p
2625, or stanza 2, line 6, word 2 (corruption), letter 5: u
3333, or stanza 3, line 3, word 3 (then), letter 3: e
2341, or stanza 2, line 3, word 4 (bless), letter 1: b
5841, or stanza 5, line 8, word 4 (Zealand), letter 1: z
4512, or stanza 4, line 5, word 1 (From), letter 2: r
This gives us the final word puebzr. Decipher using rot13 to find out what our friend uses:
