Basically the only thing that 1.03.25 requires is the Monk files, which came about in 1.03.2. To patch to 1.03.25 will require any previous version of the game which has the Monk files in it - this Any to 1.03.23 patch should do nicely. After that, it should be fine to download and install 1.03.25. The reason why 1.03.25 is so huge is because it alters the large Sound FX and Knight side XCR files.

The memory issue is one which existed since 1.03. Only 1.03.24 has managed to fix that (this is the only difference between 1.03.23 and 1.03.24), but it should rarely be a problem at all since running any of the versions in compatibility mode for XP has worked fine. 1.03.25 is based off 1.03.23 because 1.03.24 belongs to GOG and I don't think they'd be willing to share their code unfortunately.

It should be mentioned that although the 1.03.25 exe does fix vampirism from previous unofficial patches (and other stuff. The unofficial patch line broke vampirism), it also has a framerate problem which can be an issue for certain laptops and even some PCs. You'll likely need to turn Particles to Minimum or even Off altogether (either should fix the problem I hope). If there's any issues with that I'd recommend backing up files before using the 1.03.25 patch. Patching to the latest version isn't really necessary, there's plenty of people who still use 1.03 and 1.03.24 for example :).

Anyway, I hope this helps.
