Ad 1:
You could hide the ellipser […] (not sure I used that word correctly) with JavaScript. This script is from Reddit:
<script>
var elements = document.getElementsByClassName('cloze')
for(var i = 0; i < elements.length; i++) {
elements[i].innerHTML = elements[i].innerHTML.replace('[...]', '')
}
</script>
Just insert it into your “Front” template in the “Cards…” window. I adjusted it to remove the whole thing.
Ad 2:
You can create multiple cloze deletions in one card by using the same index on the clozes (shortcut: Shift+Ctrl+Alt+C):
This {{c1::card}} contains {{c1::two}} clozed words.
Output: This [...] contains [...] clozed words.
