Hi!
(I'm not sure if the 2nd and 3rd questions are supposed to be in a different topic. Sorry if so!)
It's generally best to post unrelated questions separately, but I'll try to have a look at them all here in this thread. I'll answer them in separate posts.
It looks like you've made some substantial changes to the theme. I'm curious, how did you pick Twenty Fourteen to use?
the menu doesn't appear when I view my site on my iphone. Is the best solution to download the Mobile View plugin?
Your menu is actually invisible in Firefox on my desktop machine as well, so it's not a mobile-only issue. Here's a screenshot:

It looks like you've added some code to make your menu links white:
.site-navigation a {
color: #FFFFFF;
font-size: 1.1rem;
text-transform: lowercase;
}
(Or since you changed the background from black, that would explain why the white links are not visible against it.)
Try changing the white links to another colour code and your menu should reappear.
