I love my Bilsteins - which are not revalved street units, but Bilstein Motorsport race monotubes revalved per Bilstein's recommendations. I found them to be no more expensive than the Konis, and everyone I talked to said that if you can afford monotubes, do it. They're not adjustable, but they are revalvable - and I can still tweak swaybars, alignment settings, and tire pressures. That said, I'll admit that I have not had enough testing time on them (too busy crashing and blowing motors), and you're probably better off, in the learning phase, going with something a little more tried and true. Experiment later (as I did - I also started with Konis).
I would definitely agree that you should consider non-remote-reservoir Ledas if threaded-body dampers are approved for next year (seems likely, but don't quite bank on it just yet).
Sphericals are lovely, though bushings are cheaper. OTOH, I have not seen bushings available for all the stuff that bearings are available for (trailing arms most notable glaring omission). I have bearings all around. Spend the extra couple of bucks for the Racer's Edge ones, that screw into place. It'll pay for itself when you bend a trailing arm, etc., and have to replace the suspension arm, but not the bearing. I got my front a-arm bushings cheaper from Shine, but they press in, and if I bend an a-arm, I'm gonna but in trouble.
Swaybars - I agree, go factory. I have my stock front bar, and the 19mm rear adjustable M030 bar (its not 28mm, unless I'm confusing them). They're cheaper than Weltmeister and better quality (think OEM factory quality control processes).
Springs/bars - I run 400# front, 30mm rear bar. My car, as an ITA 2.0L 924, runs at 2600#. I still wish I had more spring and bar! So yeah, this is something you only want to do once, take the time and money to go for 32mm or bigger. Front springs are cheaper and easier to interchange.
