Creating Cost Curves

Hello,
Use any following way to automatically select these particular milestones: put Indicator # n field to YES, MARK the tasks
Create a filter that will consider only those tasks
Create a Export Map with this filter
You could try also the macro "Time distributed data" to export filtered informations into Excel

You combined two thing in a single question as I understand. If you want 3 month look ahead schedule (Task) to export into excel or you want to export 3 months resource or cost profile (resources or cost data distribution) to make S curve in excel. In first case it is very simple create new filter as per your need then export. In second case after filtering change the view to task usage then export distributed work in excel. In case of only milestones also you can create new filter for 3 months. Hope this will solve your problem.
