Heya fella.
I'm afraid there's not much choice if you're sticking to the strut/spring combo.
New or used Bilstein yellow billies
(about 40% more damping than stock), used black billies
(about 20% more damping than stock, fitted as standard to many of the later turbo cars.
.
is this what you currently have?), standard Toyota fixed units or used standard rev1/2 rebuildable struts with a choice of Koni or KYB
(& possibly Spax) inserts.
As for spring if you don't want to go lower and want to save cash stick with stock, otherwise I've heard the Eibach are quite comfortable and you probably won't see a drop from your old saggy standards.
My question to you is.
.
.
if the springs have you low enough and the struts aren't failing why change them.
Would the money be better spent refreshing other things that are probably effecting the drive more.
New lower ball joints and a full bush kit to replace the probably quite worn and perished originals maybe? If you want to spend and mod how about beefing up the ARBs at the same time as doing the bushes and going for something like the Whiteline adjustables.
Whatever you do think it through.
.
.
get rides in similarly equipped cars at least.
You don't want to be doing it all over as it's time consuming and costly and you'll need full alignment done afterwards each time.
Good luck with it.

I'm on yellow billies and tein s tech springs and the ride is v v v firm.
But then the drive is fantastic.
