Hi,
I would use plug-ins for this effect:
Check out these different ones,
Flaming Pear
Eye Candy
Filters Unlimited
For the flaming Pear one I know you can find presets that you can download from the internet by doing a search. I am running out of time this morning and need to get back to the real world and work today!!
If you're familar with plug-ins you should get some good results!!

PS. hehe you should upgrade to PSP9, but remember I never used 8 so I have no idea of the differences!!! LOL Thank you for your kind words!!
