Yoda what is your server IP? i wanna join up
Oh and down to the bed rock is probally not the best idea. unless your on peaceful, TONS of monster spawners are down there.
Oh and make an obsidian farm to make portals to the nether!
Be warned though, when you come out of the portal, youll be in a different place then you built it. If its close by thats fine, but if like me its miles away and you get lost. just make a new base near the portal and hope for the best
