If funds are tight I'd break the project into two phases and use the "inside out" approach.

Inside out basically means you upgrade the stuff that is deep "inside" the suspension first. eg. torsion bars and bushings. This is a labor intensive upgrade that includes R&R of the parts plus setting ride height, corner balance and alignment. But the labor is common to both parts so do them together and do it once.

The "outside" are items like sway bars and strut braces. These items can be done as stand alone projects when funds allow. They don't require repeating labor steps performed while doing the "inside" work.

That said, I'd go with 21/27 based on your description and intended use.
