Here is the corner I’ll be tackling next for insulation (depending on an issue that will be described after the pictures):

Excuse the mess. That is what happens when you move into a house that was just water damaged and you know that you can’t really put much out as it’ll all have to be moved around at some point during restoring.
You can see the 7 and some odd pieces of foamboard I have left. Should be enough to do that little left corner, the wall on the back, as well as up to that window on the top right. However, before I can do those areas, I need to figure out what to do with this:

That bottom pipe is our water supply line (just to the right of the picture, it drops down to the floor to the main valve). The top pipe is out main gas line coming in from the meter. While the gas line isn’t in the way of the foamboard insulation, the water line is directly up the concrete. Is this too critical of an area to learn how to do plumbing or is it pretty hard to screw up? I’d like to move it through the joists and keep it out of the way. If you recommend going forward with this myself, would you do copper, PVC, or PEX? I like the look of PEX, but I’m not sure if it well suited for your main incoming water line.
The gas line I’d be more likely to hire out. I just don’t like the thought of a pin hole in a pipe leaking natural gas into my basement. Here is where the gas line comes in (you can also see another water line run):

Once I figure out how to do this plumbing thing, I’ll get lots more practice over by the washer:

That knob valve is for the exterior water faucet. Looks like at some point someone didn’t like the amount of pressure they were getting off of that line that runs to the washer so they decided to T off the main incoming water line and run one straight over here.
And here are some pictures for Todd at Home Construction Improvement. These are the boards between the joists I was talking about in the comments on the last post. They might be able to be removed. I’m not sure what their purpose is nor what is behind them. I think they are just holding in rock wool if I were to guess.

Here is a few joists over in a another area I’m not exactly sure what to do… expanding foam?

And some dreaded knob and tube wiring that is going to be in the way. They run directly between the joist and the concrete. I’m not exactly sure where they are going to be honest. Either to the porch light (less likely) or to the main floor bedroom outlets (more likely). I’ll have to look into it a bit further to determine it.
