Wat type of rock are you trying to get rid of? Size? Maybe pics? I'm looking for rock for a project... And what exactly do you mean by old Woodwork? Again, pics would help.
What at is the sq footage of your yard? Back yard sounds like a real chore, but the front yard definitely sounds like a doable project. Without pictures it's hard to tell what direction you should go in, but I'm inclined to suggest tilling up the front yd and re-sodding it.
I'm not a landscaper, but I worked for one for 3 years and I played one on TV. I also love DIY landscape projects.
