Hello,
I'd advise not to bring bulky things like furniture. Such things you can purchase when you arrive. Transporting furniture may cost a lot of money. Unless it's a piece that you cannot live without, just wait until you arrive. Also there are places that are furnished or partly furnished.
Good quality kitchen utensils, pots, pans, lamps, television, radio, clock, etc. can also be purchased and they aren't hard to find. Basically all home furnishings you can find in Accra and the major cities (Kumasi, Tema, Takoradi, etc.). Unless like I said it's something you certainly don't want to leave behind. Any electronics you bring can be used with an electric converter is the voltage is different from Ghana's voltage (220 volts I believe)
I hope this helps.
