Looking for suggestions - 2005 Tacoma X-Runner Suspension Upgrades

Looking for suggestions on suspension system upgrades for my 2005 X-Runner. I'm not looking to lift (lower if anything) and not trying to break the bank. Ideally I'm looking for a kit or part recommendations that are bolt-on upgrades, I don't want to have to heavily modify anything.

I took my truck up to a shop recently due to some vibration and other oddities after a long road trip, had them check everything out. Quoted me $8k including parts and labor, and this is just for OEM stuff. Nah. Only good thing that came from their inspection and quote was getting it up on the lift so I can see the problem areas. I have... quite a few issues.

Pretty much anything suspension related with bushings or bellows is rotted out.
Stabilizer/Sway bar end links are shot.
Front struts/springs - prefer a whole assembly, like a quickstrut. bad experience with compressing springs. never done coilovers before so not yet sure what it entails.
Rear shocks
Inner and outer tie rod ends
Steering gear assembly - bellows are gone, leaking fluid
Leaf springs are shoddy.

Initially I posted this over in the 2nd-Gen forum but was suggested I post over here for more response.

Thanks!
