If you're going to drive it, here's what I would do:
First do a visual inspection. Look for any rodent nests, chewed wires etc...
Try to siphon out or drain that old gas and put new gas in it.
Also pull the plugs and spray a little "fogging oil" or WD-40 into the cylinders because they're dry. You could score the cylinder walls if you run it dry. That will lead to trouble in the future.
Check the engine oil, if it's 5 years old, I would change it.
Check the coolant level. You can use a hydrometer (very cheap tool) to check if your coolant is still good.
Check your brake fluid, and other fluids.
Check your brake hoses, coolant hoses, etc...
Replace the battery, remember connect the positive first, then the negative. It will probably run rough for a while because the computers will have to re-learn everything.
Also, I would not use starter fluid to try and start it.
Good luck!
