Engine Help, car needs check up, sitting for awhile

#1
My baby girl is rarely driven. 70k miles since i bought her in 2006. I had the water leak issue but I think its fixed anyways been trying to do some maintenance to try and get her back in tip top shape. Im wondering about my suspension. Do my struts and shock need replaced after so long despite only 70k miles? I have eibach springs, a cai, changed the filter and cleaned the maf. A sct tune, do i need to update that too? I replaced the radiator fluid a few yrs ago around 65k. What do you think about steam cleaning engine.. bad or good? I live in the desert so dusty. She just needs a check up so not sure what to think about replacing. Check hoses, ect. Any thoughts?
