Generally speaking:
<$25 = camber bolts (Subaru or SPC)
<$75 = alignment
<$250 = strut tower bar (Grimmspeed, Whiteline, Cusco, etc)
<$300 = differential bushings/inserts + braces
<$500 = sway bars (Eibach, Strano, Whiteline, Hotchkis, Perrin)
<$750 = quality tires (RS-3, ZII, PSS, RE71R, etc)
<$1500 = springs/shocks (Bilstein/Koni + Swift, RCE, spring of choice)
<$1750 = differential (1.5 way OS Giken)
<$2000 = entry-level coilover (Bilstein B14, Fortune Auto 500, RCE Tarmac Zero, KW V1, ST Suspensions, Tein Flex series) + rear lower control arm (SPC, SPL, many others) + camber plate (if needed, HVT or Raceseng)
~$3000 = high-quality coilover (Ohlins R&T, RCE Tarmac II, KW V3, Tein SRC, MCS TT1, AST 4150, Mann Engineering)
unlimited = chassis bracing and bushings (front and rear subframe seems to be good targets)

Hmm, is this list meant as upper levels including lower ones, or one has to sum their prices? From prices it somewhat seems that it's later case.

Order of importance? (my opinion, which is likely wrong)
1) Camber, alignment, and tires
2) Springs/struts or Coilovers (depends on budget and driving style)
3) Sway bars
4) Bushings
5) Chassis bracing (including strut tower bar)
6) Differential

However wrong or not Mann's & yours is, they can help to start with suspension purchases for newbies, unlike most threads that review/write about single suspension component, or at most - few of same type, leaving out overall relative-inter-component importance/gain comparison.
