I assume then that you feel it has suffered in handling in the last few years?

If your interest is handling, fsport shocks and springs are probably the first place to start. Maybe coils if you want to lower it as well, but the fsport shocks might be a better bang for the buck if you can find them and aren't interested in lowering the car much.
Next would be the rear sway bar, then the front, but if you go fsport I think you can only buy the front with the rear, so if you have the money, get both now. Down the list is the underbrace, again fsport might be the best choice, and finally there are a few stiffening components. Jun-tw sells an 8 piece kit or separate front and rear kits. I have them on mine, but I can't say I've noticed much of a difference.

You should also consider a limited slip differential, if you have the cash. That is the most expensive part and also the most fun.

I would get the ISF steering ECU either before or after the sway bars.

Coilovers - $1000+
Sway bars - $400+
New "FIGs" bushings - $500 at least for the front LCA bushings and the rear diff bushings, but there are plenty more available!
IS-F steering ECU - $400
Great tires - $1000+
OS Giken or ATS LSD - $2700/$1400

Hope you have money!

What is your budget? You will need at least a set of new shocks if you are on the originals. KYBs are about $400 Tokico Blues are about $550. Any other shocks (Koni) will go up in $. FIGS LCA bushings for the front will help too or at least new factory LCA bushings. Michelin PSS tires are very good. Just make sure you are all aligned to preserve the inner front edges. FIGS will help with that. Good luck and open your wallet :-)

Best parts you can find and "budget" shouldn't be in the same sentence.

Is-f steering dampener, fsport front and rear sway bars & chassis brace, sticky tires, is-f steering ecu, coilovers, light weight wheels, remove the spare tire... All these will help with handling

Granted I do not own an IS, rather a gs. But from experience I would start with the swaybar(If decently priced [$150 - $200]). Then progress from there. It is generally known that the swaybar is hands down usually one of the biggest handling mods you can do out of the box for a moderate to low price.

Start with sway bars both front and rear if you're on a budget and then go from there.

If you want the best coilovers, you're probably looking at Ohlins which is on the figs site for $2772.

Like a poster above said, budget and best do not belong in the same sentence. However the coils are fully rebuildable, with 2 years warrantee, and hand built to order.

^Glad to see someone with the Ohlins setup; like you said, best off-the-shelf coilover one can get for the 2IS. Have you played with compression AND rebound valving? My next "suspension" project is the FIGs LCA bushings and maybe an LSD later in the year.

Honestly I never found the need to. I turned the damper all the way stiff and it was way too hard for daily driving, so I'm about 3 clicks off full stiffness. However, I'll tell you this; the DFV (dual flow vales) in the ohlins coilovers makes my 20 inch rims with 30 side wall feel like 40 walls. My buddy drives a 2012 CLS550 with stock air suspension on 20 inch rims with 30 walls and even at its softest comfort setting, it still feels like a mine going off whenever you hit a divot in the road. Even he is amazed by the coilovers. The ride is amazingly more comfortable than stock by a longshot.
