Well i have also just got a 98 fiesta (first car - had it for 7months) and i can help you out on these. 1)To find the the colour code of your car i would check either your MOT certificate or your registration document. (Somtimes it is also in your car book.) If you still cant find it go to a local garage. 2)The best scratch touch up is proberlys from halfords, with the coloured pen. A tip here is not to buy a cheap one, they dont work as good. 3)If your after standard wheels for your fiesta, i would go to a local salvage yard. You can get some really top qualiy gear at a decent price. 4)I have the exact size tires and to be honest i only buy michelin or goodyear tyres. 5)Once again try a salvage yard for a spoiler or even ebay, but if i was you i would not bother getting one, there is alot of work just fitting it, if your fiesta comes standard without one. Any other questions just PM me ill be happy to help.
