It will work, but it will be pretty sluggish. I would recommend something like an i5 or maybe even an i7 if you can save up to afford it. As for the editing tools, Paint.net for picture editing (GIMP is good too), and Windows Movie Maker are my favorites. Paint.net gets the job done for most editing tasks like cropping, changing color tones, adding text, etc, but for anything intensive, you might want to use Photoshop. WMM is fine for basic editing, but you can't do many effects.
