Hoses to replace when changing valve cover gaskets

2000 Tacoma 3.4 V6 4WD

Could you guys help me in determining which hoses to replace when I replace the valve cover gaskets.

I would like to have some replacement hoses ready before I start, so when I start taking hose connections apart and they are cracked due to being 13 years old I can replace them without leaving the engine wide open for days.

If you have experience in changing the valve gaskets, and know which hoses need to be removed in order to remove the plenum, etc. (so I can go to the parts store and ask for these ___ hoses) could you give me a list and or a pic?

Thanks
