About the Wiimote-Desynchronistation: Use the emulated Wiimote. Just untick Connect Real Wiimote and Use Real Wiimote and play with your Mouse and Keyboard. The error should now appear not again (normally).
I hope you used a real wiimote till now, if not... try out using a real wiimote instead.
About the savestate: actually there can be a safestate after a part with a critical error because you can dump saves from your real wii that can be used in dolphin.
