Here's what I took last time I did it:
And my stats were this at the time (drank super set just before entering, i probably took this after a few bats hit me because of my lowered prayer):
And here's what I had left after I finished. As you can see I didn't even use up my first crystal bow, the 2nd went untouched until I got to Jad (wanted to use the full bow for jaddy):
I found you should try and get as much ranged bonus as you can, it actually helps a lot in finishing quicker and seems more useful than prayer bonus.
You might want to take a couple more super restores/pray pots than I did because your ranged is a bit lower.
Hope that helps.
