I could be wrong, but I don’t think it is possible, reflowable and FXL both have their own UI/chrome and I don’t think it’s possible to use one for the other.

Unfortunately it’s not possible, you have to use a span tag and class to do bold italic text on ePub Export. If you need/want to edit the HTML/CSS I would do a GREP search for your span tag <span class=”[your-bold-italic-class]”>(.+?)</span> and replace with $1. This is something that bugs me too, so for all my ePub Exports I go in and clean up all the , , and <sup> tags that have classes (that I dont want to have classes) and any spanned classes that I can convert to semantic mark up such as bold italic. Hope this works for you.

Unfortunately there is not a inside gutter setting in InDesign like you are referring to (or at least one that I know of), I would adjust your inside margin on your master pages so that it is adequate enough so that nothing will be printed within the inside edge gutter (or inside margin in InDesign) when placing your text frames. You can adjust your margins on your Master Pages after laying out the book with Margins and Columns (with Enable Layout Adjustment checked) but you might have to go and make sure everything has adjusted properly.

Wow, that doesn’t sound fun :( I would probably be in the same boat if it were me as I’m not familiar the color profiles end of InDesign. I did a little searching (as I was curious and would want to know what to do if I had the same issue) and found another form post on here that might be of help.

Just off the top of my head, this should work though

Find: (\d)(\d+\.\d%)(\d)(\d+\.\d%)(\d)(\d+\.\d%)
Replace: $1($2)$3($4)$5($6)

Yeah I usually have to go into my InDesign exported ePubs and fix up the code on images. I normally set my images to be centered and, if possible, stretch the width of the page, unless I’m floating or something else, but this gives me a good base and a starting point to do more if need be. you might try this and see if it works for you. This also works on the iPad, though for centering issues, you would need to wrap the tag in an empty span tag.

CSS:
.center {
text-align:center;
margin:0;
text-indent:0;
}
img {
width: auto;
max-width: 100%;
}
div.image {
text-align:center;
}

HTML:
<div class=”image”>

</div>

Kindle also requires a guide start location as it will not, and cannot be set to, open to the cover, so if your forward is the first text file after the cover, its probably a good chance this is the reason. You can set up a guide section in the OPF file to direct the ereader to open to another part of the book, as long as it is not the cover. You would also need to set an id=”start” in one of your tags in your file as well.
