Eagle newbie questions

[mmormota]

Hi!
I just started with the Eagle pcb sw, and I have a few questions:
- how to place smd components to the bottom layer?
- how to "unroute" the autorouted board? (I mean remove all of the tracks)

I need the following library element:
- a single pin connector (wirepad)
- solderable copper rectangle (no solder mask on it) enforced by 4 plated
holes

How can I do it?

My unsuccesful trials:
1, build it from 4 pads and a smd
errors: can't remove the pin names, so it counts 5 pins, drc clearence
errors, terrible
2, build it from a smd and 4 holes
error: drc error: dimension
-what is the meaning of this drc error?
-how can I control wether the hole is plated or not?
3, build it from a rect and 4 holes
error: can't give name to the rect, so can't connect it
