Hey novelas_,
First of all I would set up a test library so you won't corrupt files trying to get things right.
Second set up at a colunn to save metadata. Set it up as long text, like culumns and then under customize fanficfare, at the bottom of the Customs Columns tab set "Saved MetaData Column" to the column you just created.
This allows you to rapidly update from the saved metadata column as you figure things out through trial and error without hitting the site over and over again.
How do you know which tyoe of column to set, that all depends on what you want to do. Start by browsing this forum for exmaples, there are many.
To give you a starting point, for wordcount and pages? I set mine as integers.
For status and different fandoms for example I use Comma seperated, like tags.
And for notes I would set as long text like comment.
And anything date of time related, use dates of course.
For a read status I'd use a Yes/No type of column.
As for your personal.ini file, start with reading the comments under the defaults Jimm has set up. There are many tips on basic settings and in addition read
