We have a terrible sewage smell that takes over our house. This only happens when water is drained through our main floor shower. (We live in a ranch style home built in 1958.) The smell however comes from the basement bathroom. I can't tell if the smell comes from the shower drain or toilet. Not sure if this is related at all, but our toilet in the basement ocassionally bubbles when the washer is going.

We have completely stopped using our upstairs shower for a long time now and I would really like to be able to use it again. We haven't had the money to call a plumber out, any solutions?

Each fixture has a trap with water in it to prevent sewer gas from entering a home. (A toilet has a built-in trap.) Each trap has a vent pipe (ultimately connected to a vent pipe through the roof) after it in the Drain/Waste/Vent system to break the vacuum in the drain line.
When a vent pipe is blocked or partially blocked with a birdnest, cobwebs, leaves, pinestraw, debris or trash, it prevents the vent from working properly.
When waste water flows through the system and a vent is blocked, it will create a nearby "vent" by siphoning trap water out of a fixture and that drain trap without water in it allows the sewer gas in.
Have someone go up on the roof to check all vent pipes sticking up from the roof. Clean out all debris, leaves, etc. that can be reached by hand and flush it down with a garden hose sprayer.
If that doesn't solve the problem, you may have to rent or borrow a heavy-duty plumber's snake to snake down the vent pipe to break up the debris and clear it, and then flush it with a water hose.
Once blockage is broken up, it should flush on down and out of the system to the main sewer or septic system.
Good Luck!
