First, I want to applaud you for trying breast feeding!! Stick with it, you won't regret it. I nursed both my girls until they were about 15 months, and it was such an awesome experience. That said, at the beginning, it's not awesome, usually. :) As some other posters have said, engorgement (huge and hard breasts), with some pain, too, is totally normal at this point. Your body hasn't regulated your milk supply yet to match what your baby needs. So because of that, I would be really careful with the pumping. I had to pump at first to help my babies latch on, because my breasts were over-full, but you only want to pump out just enough so that your nipple is a little softer. Your breasts work on supply and demand, so if you pump a lot, and then your baby feeds, your body is going to keep producing all that milk.
I think a warm shower is a good idea - let the water run over you for a little while, and massage your breasts to let some milk come out. Like some other posters have said, if you have a red area on your breasts, and you have a fever, you might be developing mastitis. Call your ob/gyn right away. This is not a fun complication and you need to get on antibiotics ASAP if you have it.
Don't take ibuprofen. It's not great for nursing mothers. I would be very careful with the cabbage, as it can completely stop lactation. Also, I'm not sure that you should use honey at all. Remember that infants should NOT have honey, so if you were to use it on your breasts, you would need to clean them thoroughly (mild soap/water) before your baby nursed.
If you just continue to nurse your baby at regular intervals, and use the hot shower and hot compresses, your engorgement will go away in a few days to a week, most likely. You shouldn't need to use any other remedies. However, do call your doctor if you have a fever. God bless, and congratulations!!!
