Joomla Attachments

I own the premium version and all the add ons and finished the migration of one site. Three Questions,
1. I have a sit that uses the Joomla Attachments add on. Does your great plugin have the ability to migrate attachments which are attached to Joomla pages? I have about 400 Joomla articles, each has an attachment.
2. In my last migration I had to choose between migrating Joomla content either as all WordPress posts or pages. That is not too bad as 99% of my content should go over to WordPress Posts, except for terms and conditions, the home page, quick links, sign up for email pages, etc. Will a subsequent version of the plugin allow me to set the Joomla article ID’s that I want to come over only as pages and the rest comes over posts? In my last migration I had to run the tool twice, copy the WordPress database, and then merge the entries I wanted as pages. That was not terrible, but took more work.
3. I am using SH404SEF and your plugin for that. Which plugins do I need to run long term on the new WordPress site once I am done with the migration? On my first migration I used some database queries to write redirects in Yoast SEO so that I was able to uninstall the FG Migrate plugins.
