I would get the rear shock sorted first, if on a budget definitely investigate the R6 shock option, PM Devilsyam for the details. The cheapest option would be getting the OEM shock regassed and resprung, this would make things better but obviously not as good as the next to new shock that Luke could supply you with.
Front springs are either linear or progressive, progressive seem to be the popular option and are available from a wider range of manufacturers, they are more of an all round setup for comfort and handling whereas linear are more focused on handling (at least that is what I gathered from my research). I went for linear as I believe they are better suited to my riding style and requirements and I got my springs (plus seals / bushes / oil) from K-Tech. If you Google "motorcycle fork spring calculator" you'll get a few sites where you can put in your details and get some recommendations on what rate spring you should be looking at i.e. http://racetech.com/ProductSearch/2/Yamaha/FZ1/2001-05 (calculate spring rates - under Fork Springs & Kits).
