Advice needed for combining repairs

[luvmy03E53]

I'm in the unfortunate situation of having a leaking oil filter housing gasket, leaking steering fluid hoses or reservoir, and needing to replace the oil separator and hoses. My question is this: Does it make sense to do all of these repairs in the same session? I've started the OSV repair before but got frustrated with getting everything out, so I gave up. I have a hunch that getting the oil filter housing and steering fluid reservoir out of the way will greatly simplify getting the OSV and hoses done.

As always, any advice is greatly appreciated!

Almost forgot... I have an M54 engine.

Thanks!
