lowering questions

[76bonanza]

This is my first lowered truck so I am new to this. And I have a few questions. Frist my truck is lowered 3-4 4 inch blocks in the rear and 3 inch lowering springs in the front.

My questions are for the rear since he used 4 inch blocks to lower it are the coil springs and shocks still stock hieght and if I shop for shocks for the rear I should get stock height ones? What about the tracking bar should it be adjustable? there is one on it now not sure if it is stock? If I get a rear sway bar will it matter about the drop? Also I see shock relocation kits for 4 inch drops this would not apply to dropping with blocks correct?

Now for the front shocks should be for 3 inch drop right? Also there is no sway bar on front this would be a good addition correct?

Sorry for all the questions just making sure I understand.

Thanks
