Those items no longer drop. Some are tradable so you can farm plat and attempt to buy them however.
Kunark is about to open so there are some opportunites to get some of the pre-nerf items that came out with that expansion like the sk/necro invisibility hat or inventory usable fungi staff.
I can't speak for the devs but as of now they haven't mentioned opening a new server. The current plan is to take this one through velious which could be another couple of years.
