The first problem is that Minitool is rubbish. We recommend GParted - there's a guide to using it in the All Things Root Guide sticky post. I tend to trust 4Ext Touch recovery to partition cards as well - more so than CWM (but I trust that much more than Minitool!). You should also use Ext4 or Ext3 rather than Ext2. As for the rest, I need to read your post again (on TapaTalk and was interrupted).
