Any reason you didn't go for 14.04 LTS? It should run fine on a CPU with 4 cores (though 4Gb isn't much for a KDE4 desktop).
What KDevelop version are you using?

I don't understand why you have to import the project file by file. Even if it doesn't use cmake there should still be an importer for projects based on autoconf or even a simple Makefile.

I see 2 options if KDevelop 4 cannot work for you:
- build KDevelop3 yourself, supposing you have or can get the KDE3 libraries and other dependencies installed
- Check out if Kate doesn't cut it for you. It sounds like it might, it does have some form of project management, and does do highlighting.

Other options that involve more drastic changes would be to try Qt Creator (but you'd get an obsolete version from Ubuntu) or find a distribution based on Ubuntu (12.04) but with the Trinity desktop.
