Custom Fields for galleries

[islander]

I am new to GS and am blown away with what it can do. Thanks to everyone who has helped develop this.

My questions are, I would like to add galleries to some pages (probably with I18N Gallery), but would like to avoid having place holders in the editable section of the page where users my delete them. Apart from adding a new template style, is there another way, possibly with I18N Custom Fields, so that it wouldnt be so easy to screw up?

Is there any way to lock some pages from editing so that only admin can modify them? (possibly with multi user plug-in)

Thanks for any input that can be offered.
