I am currently in the process of replacing my L28 N42 valve bushings. I was wondering, since I'm going to have the valve cover off, where I might be able to buy some new stock valve springs. Also, would I need to replace the valve cover seal? And, after I replace the valve springs, do I have to replace the valve retainers and lash pads as well?

"new stock valve springs:", Nissan ?
"valve cover seal" maybe, depends if you wreck the one on it when you take the valve cover off
"valve retainers", I haven't on the few heads I have done the seats on
"lash pads", only if you change the height of the valve, but if you check the wipe pattern, it will tell you, if you need to change the thickness.
heres a link with some info on wipe pattern

here is another good site to help you through the process. It is very important to keep all your valvetrain parts in the order in which they come out. Look at them as "matched sets" that cannot be inter-changed. There is a big difference between valve guides and valve bushings.
