Definitely take Typhoid vaccine orally. I also got the Hepatitis A. Hepatitis B is not necessary. Polio has almost been eradicated from the world, so I doubt you'd need that. I've heard that the malaria prophylaxis treatment can react weirdly with diving, like psychologically, weird dreams, messes up your brain. I have no personal experience with this...just what I've heard. So I've never taken it.
I'm a mosquito magnet, too, and I wear a lot of mosquito repellent and permethrin treated clothing, stay in the air-conditioning at dawn and dusk, and travel with a small fan. I place the fan on the table when I'm eating to keep them at bay. Air movement helps to keep them out of your face while you're eating.
For good measure, it would be a good idea to get your vaccines at intervals before your trip so you don't have any adverse effects of mixing all those vaccines into your body at once. Also, if you happen to have an allergic reaction to a vaccine, you can pinpoint which one it is if you've only done them one at a time.
