In order to install a different kernel you need to root the phone - rooting is the part that voids the warranty.
The superuser account name on any unix variant is called root - as the root user, you're free to configure the system however you prefer. This is identical in concept to having Administrator privileges on a Windows PC.
For all intents and purposes, Sprint owns root on your phone as opposed to you. They don't like people changing that, so they void the warranty.
There's no real danger to being root - except for the bozo cases where someone decides the point of root is to destructively remove essential processes and then whine to Sprint to fix it. (And you can make your phone equally goofy just using a task killer abusively, so it's really not something to loose sleep over, in my opinion.)
You can also back root out and never be detected. Theoretically, you can root, and back out and still have warranty coverage. In my case, I thought in the back of my mind that made a good safety net. Instead, I so prefer the advantages of root, I've emailed Sprint's CEO that I'm rooted and so there's no question in anyone's eyes that I have nothing to hide and prefer my freedom over my warranty fears. You'll have to let your conscience guide you on what's right for you.
But back on topic - yes - with the right configuration, input tracking is vastly improved. That really and truly is a separate part of the code, but because of how things are architected, it gets tied topically to the fps cap.
Here's a vid made by jmxp69 - he's a kernel developer and so all of his posts in this thread you can accept as "from the horse's mouth" - iow, firsthand _knowledge_ as opposed to secondhand info (such as myself) -

The vid in the first post shows some fps stuff, and other posts of his on that first page tells the _true_ story of what does and doesn't relate to the HDMI port, as well as provide the negative comparison of the stock EVO to Droid X (and uncripped Nexus One, that runs our same processor (variation only due to GSM vs. CDMA radio controller)).
In your case, ShoxV, you'll want to pay particular attention to the video in post 53 on the second page of that thread - it shows the finger tracking - with a comparison of custom to stock.
Don't be discouraged about stories of things not working in custom kernels. That varies by custom kernel and these last two months have nearly been an eternity in kernel development and evolution - the kernel devs at XDA are really quite excellent. (_Everything_ works on my phone, in other words.)
And a final note on 30 vs. 60 fps - 60 fps is _not necessarily_ the holy grail.
Virtually everything you've seen in any American theater - and virtually every movie you might have on Blu-ray - is at 24 fps. The only time you'll actually see 720p at 60 fps is when you're watching an HDTV channel dedicated to that performance - typically, that's the realm of sports broadcasts (or your own _higher quality_ HD camcorder).
Even DVD movies are 60 _fields_ per second - the result of telecine processing of a progressive 24 fps source into the NTSC interlaced field spec of 60 Hz.
That means that if your concern is movies, anything in the 30 fps is aok - not because that's all the eye can see as HTC claims, but because that's what our movie source material typically does.
If you're a purist, then 60 fps is the ATSC holy grail. If you're a more typical user, then 30 fps for 2D content is completely sufficient.
If you're a true gamer with a hardcore Windows PC setup, you already have a gonzo system set up for 90 fps and beyond, with 120 fps not being uncommon.
If you're unrooted at 2.2, you'll have to wait for the root exploit to be announced - novox77 is tracking that for you here -

Hope that's helpful and not too opinionated.
