Plumbing systems require a vent pipe that runs up through the roof of the house to open air. Venting avoids the siphon effect where one appliance draining causes suction that drains another appliance. If your vent stack is plugged it could cause the bubbling/draining of the toilet. Larger houses with large plumbing systems may have several vent stacks. There will probably be one directly over the problem bathroom. Start there and make sure the vent isn't blocked. Sometimes birds will roost on these to enjoy the relatively warm air coming up from them. If a bird fell in the pipe it could be hard to tell without running some sort of snake down the pipe.

You can drain it directly into a drain pipe. Just make sure the the top of the drain pipe is even with the top of the washing machine. If not, the water from the washing machine will drain all of the time. There is no valve in the machine to stop the water from draining. The washing machine drains using a pump motor.

Can one successfully plumb a sink drain into the standpipe for a washing machine?
Yes you could, but it's usually not allowed by plumbing codes. Another point: Sometimes in Britain the outlet from a washing machine is joined to the under sink waste. I lived in a house with this arrangement once, and every time the washing machine was on you got bad smells from the drains, so I wouldn't recommend it.
