you have 90 days which is plenty of time to see all those places well. Not sure what else to say really though as you dont really ask a specific question we can help you with. If you can provide more info on what you would like to know Im sure we can give you some good answers.
Maybe post a rough planned itinary as many people do and we can let you now if it look good and/or make suggestions on how to improve it.

My itinerary as I had thought of-
1.Santa Cruz(3 days)

2.Sucre(2 days)

3.Potosi(confused whether should stay overnight or include it as day trip from Sucre)

4.Tarija(2 nights)

5.UYUNI(3-4 nights)

6.Oruro(2 nights)

7.Cochabamba(4 nights)

8.La Paz(3 nights)

9.Copacabana(4 nights)

10.Copacabana(confused whether to make it as day trip from La Paz or stay overnight)

11.Rurrenabaque(4 nights..confused whether to go for jungle tour or the pampas tour)

12.Trinidad(1 night transit)

13.Santa Cruz

I would like to add Corioco just for Death Road experience(might as well do it before it disappears) but dont know how to include it in this itinerary.Is it possible to visit Sajama National Park in a day trip from any of the places mentioned in the plan.If not how can I add it as well.Please let me know if the number of days for each place is sufficient/too much/too less.Advice on UYUNI and RURRENABAQUE tour opeators.

Most importantly,please help with the transportation part.I have got plenty of time.So would like to go cheap(road/train travel) and experience Bolivia
(Phew)...know that's a long list.Thank you for your help tunabagel.Really appreciate it.
