Depends on what?
I will be making an amp by bootstrapping an LM3886, and adding an output stage. I'm not yet sure how many transistors I will use in parallel, but it probably will no less than 4 per rail.
How does the accuracy thing work? If a resistor is 0.1 ohm 5%, then do I multiply 0.1 times 5% to get how much the value will vary? So this resistor's value would be between 0.095 and 0.105 ohms? Or is it 5% of something else?

Correct.xplod1236 said:If a resistor is 0.1 ohm 5%... this resistor's value would be between 0.095 and 0.105 ohms
Depends on the application of course.
If the voltage difference is not ok when you calculate with maximum and minimum possible values in the +/- 5% range, get a whole bunch and do some comparing and matching.
If you have cheap/free output transistors, try it and see if anything blows up. Use a cover though!
