Botox for blogs

I've finally done it. I have given angrypenguin a facelift, thanks to Blogger's upgrade-to-Google facility. I am pleased with the crisp, clean look.

Of course, I am having problems in this new, much-overdue template change. Blogger says one can access the original blog to get at template adds, but now I can't find it. Maybe this is because I made more than one change to the template as I moved over. Seeing my original choice in full-screen, I realised the column width was too wide for easy online reading and sought a narrower column - this template. That is a flaw in the preview facility - the small window gives a skewed perspective. The design looked dramatically different when I adopted it.
So, all my logos, my counter and illustrated links are gone - along with the link Blogger originally offered to my archived original blog. I've scoured the Help lists - to no avail.
One always dreads making any changes online - it is never problem-free and ends up being really time-consuming. I am a content expert, but never claimed to have much aptitude for the techie side of the WWW. So here I am, floundering.
