Level drain resistance is mostly unnecessary because the MC3 from your cloak will stop 99% (or some very high percent) of attempts to level drain you.

Int shouldn't really matter as a valk as long as you aren't going to get instakilled by mind flayers. The elven helm is fine.

Pets are unnecessary, I've ascended 5 or 6 times and never used a pet past the first few levels.

Keep boots of speed, they are better than intrinsic speed.

What rings do you have? You need levitation for the air and water planes, conflict is very useful on astral, and free action is worth having too.

Teleport control is great if you find a bunch of tengus or whatever to try and get teleportitis. Otherwise, yeah, that's about it for rings.

If you have scrolls/marker charges to spare, but it's not really that big of a deal. I assume your armor is maxed out? You should be more than fine, the game is really not that hard from here on out unless you do something stupid.

If you want a good MUD design, take an Iron Realms MUD and remove the shitty parts!
