It really depends on what you want out of the springs and suspension setup.
An Eibach Pro Kit will lower the car on average 1.5", though some have seen a smaller drop and some have seen a slightly lower drop, it varies by car.
The Pro Kit has more lowering characteristics than performance oriented characteristics, so if you're primarily going for looks, I'd go with the pro kit. It won't slam the car down like Eibach Sportlines or H&R Super Sports.
Eibach Sportline springs will lower the car more but are way stiffer and can make a long ride fairly harsh on bumpy roads.
H&R Super Sports have both ideas in one spring. They lower the car 1.6-2" and have more handling characteristics built in. They are stiff, but I'd say not as stiff as Sportlines or H&R Race springs.
Either way I'd definitely consider replacing shocks/struts. With any of these spring setups you're going to change the rate of the spring enough to bring excessive wear on your stock shocks/struts, and at 101k miles, they've probably had enough wear.
As said, CC plates are also a must to prevent camber and uneven wearing on your tires.
Also keep in mind that springs will settle after a week or 2, sometimes a month...so a Pro Kit may only drop the car 1" initially, but it might settle down to the stated 1.5".
You'll also want to get an alignment, but I'd wait until the springs settle, unless you drive the car a ton such as a daily driver.
