It's not really difficult. It's just kind of a long process, and all the screws make it a bit annoying. Rough steps:
I ended up with the trackpad in and the thinkpad halway back together while trying to get the drivers to work because I didn't do a lot of research for the process to get the drivers to work. I think some steps have to be done while the clickpad is still connected (disabling automatic trackpad driver installation and such), but I'm not entirely sure. As soon as it worked for me, I just put it back together.
Edit: I'm using mine on Windows 10. I haven't tried my trackpad with any Linux distribution. This is the one I got: https://www.amazon.com/gp/product/B01NCNGBDL/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
It's a Synaptics trackpad.
Hey don't get that one lol. Apparently it's the cheap version. You'll want the Synaptics version. That would be this one.. https://www.amazon.com/gp/product/B01NCNGBDL/ref=od_aui_detailpages00?ie=UTF8&psc=1#customerReviews
I don't have a part number for the pad, and I'm relatively sure it's a knockoff of some kind. However it has been working great. I ordered it from this listing: https://www.amazon.com/gp/product/B01NCNGBDL/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
The backlight on my keyboard does indeed work, but it worked before, and all I did with the keyboard was remove it and put it back after the new trackpad was installed.
The wallpaper is from u/lostwithtrackpad, found here: https://www.reddit.com/r/thinkpad/comments/6vgucy/exploded_thinkpad_t440p_wallpaper/
I got mine from this page on Amazon: https://www.amazon.com/gp/product/B01NCNGBDL
It worked perfectly for me on Windows 7 after installing the driver from the t450 support page.
I haven't had great luck with it on Windows 8.1 yet. Different versions of the driver give different trouble. The most recent driver kills the hardware buttons, but everything else works. The older version I'm using how has everything working except for dragging with the hardware buttons.
If I get it working before my SSD gets here (and, thus, gets Windows 10 on it), I'll post what I find.
I'm not sure in which part of the process you are, but I switched the trackpad on my T440p yesterday and I followed the instructions provided in an Amazon review here: https://www.amazon.com/gp/product/B01NCNGBDL/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1#customerReviews (I also bought this trackpad, if that matters)
For step 2, I believe I did this: https://www.howtogeek.com/263851/how-to-prevent-windows-from-automatically-updating-specific-drivers/
Even though I just did it yesterday, the exact process I did seems a little vague. I can still try to help though.
I used driver package gggr03ww.exe. The link for it is: https://download.lenovo.com/pccbbs/mobiles/gggr03ww.exe, which I found here: https://www.reddit.com/r/thinkpad/comments/8gkfyt/replaced_t440p_trackpad_with_t450_trackpad/ OP's Edit 3
I got this one for my T440p: https://www.amazon.com/dp/B01NCNGBDL/ref=cm_sw_r_cp_apa_i_2doWCb10S7RN3
It's a synaptics. Never had any issues with it.
Did you know Amazon will donate a portion of every purchase if you shop by going to smile.amazon.com instead? Over $50,000,000 has been raised for charity - all you need to do is change the URL!

Long story ...
I got a genuine Synaptics trackpad from Amazon, at considerable expense (compared to other options), that was absolutely horrible. 25% of the time it wouldn't enumerate. When it did work, the quality of the tracking would drift over time. Sometimes it was OK, at others it would have too much inertia and overshoot my intended target. It would also have poor precision. I had to move away from a target and re-approach it, because I could not make small movements.

Somewhat discouraged, I took a chance on this one:

This is an Alps pad, about 2/3 of the price, and it is absolutely brilliant! It has a perfectly smooth surface and excellent tracking. I absolutely love it! Unfortunately, they are sold out. : (
I now have a bud who wants me to perform the same surgery on his T440. This one looks like the Alps that I have, so I've flipped a coin and ordered it:

But, it is still in transit from China. It'll be another couple of weeks, before it arrives.
I know you mentioned spending as little as possible but I just purchased this trackpad earlier this week and installed it yesterday followed by installing the Synaptics drivers and everything is working exactly as it should.

Personally, I'd replace the touchpad. While you have it apart you can clean any mineral deposits or corrosion with isopropyl alcohol. I think the Trackpad is about $30.
