The wheel look like it's a traditional 32 spokes one, which mean it should be more than enough to handle what you throw at it.
You should look into bikepacking, there are other method of keeping the cost down (as well as weight) without resorting to buying panniers and rack that'll make the bike feel horribly noodly.
Look at Alpkit for some selection, basically a backpack for your bike;
