Answer 1

Hoping you are using 64-bit of Java SE 1.7.0 and so advising the following.

1. go to Eclipse->Preferences...->Java->Installed JREs
2. click Add...
3. Select Standard VM
4. paste /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home into JRE home
5. Change the JRE name to something useful like Java SE 7
6. Click Finish
7. Check the check-box next to your newly created JRE.

You would need a restart.
