If you want to consider the Zimbabwe side in Mana Pools like you originally mentioned then you should consider Ruckomechi. I mostly say this because you are a single traveler and they have a set program. This camp is owned by Wilderness Safaris and, from there, they operate a group departure canoeing trip (3 night/4 day) many times per year. Matt, an American at our company currently on a conservation furlough, was staff on this trip in 2010. After the trip you could spend one night at Ruckomechi then transfer over to Goliath to hike for a few days. It is a good program.
You could also contact Vundu, a privately owned camp in Mana Pools that specializes in canoe safaris. After the canoe portion you could transfer 15 minutes to Goliath. Or, you could spend all seven days at Goliath and mix & match the canoeing and hiking as they offer it.
I was at all these camps in 2011. October is going to be REALLY hot so go in September if you can.
