Need help – customization, design, widgets and other questions

Hi all,
I have recently installed Classifieds theme and now I am struggling with its numerous options and design customization as well. So, I have prepared many different questions and need your help. If you are willing to help me, I will send the questions to your email. Thank you. Dario
p.s. also, I am having some programming/design customizations to do and I am willing to pay for this job.
