8 to 9 speed modification

I'm new to the cycling world. I currently have a 2004 trek 1000 with a 3x8 setup. It is a solid bike and I'm looking to upgrade to a set of shimano sora 9 speed shifters because my shifters are old and need replacing. I believe I've done my homework on what I need but I'm looking for some extra input. I Am all set to buy shimano sora 9x3 shifters and 9 speed cassette. From what I can gather spacing will not be an issue. I just had the rear derailleur replaced after the original one broke. It is a shimano sora, and my question is will that derailleur work with a 9 speed cassette or do I need to purchase a new one? Thank you for any input. (Yes I know many may say "just buy a new bike" I intend to later on but money is not plentiful enough to do that right now)

Yep, you'll be fine. Make sure to get a new 9-speed chain, too.

For not much more money, you could go to 10-speed Tiagra, too. I like the Tiagra (and higher level) shifters because they upshift with the brake lever and downshift with the little paddle- rather than the button on the side like Sora. Just an ergonomic difference that I prefer, not that it's better or worse...

The new sora shifters do have the paddle and not the thumb button. That was the selling point for me over finding old 3x8 shifters

You're golden, then! 9-speed cassette, 9-speed chain and the new shifters will work great with the rest of your drivetrain.
