1) Yea, you could. But in terms of syncing data between the SQL database and flat file database would involve some tweaking of the scripts. I would not recommend using both since there is a high risk of inconsistencies between the Links 2.0 and Links SQL version.

2) Unfortunately, the installation documentation is written for Intermediate Perl programmers who have some knowledge of how relational databases, like SQL, work. Although the installation scripts are pretty to use and many novice programmers have faired well with Links SQL. So, to answer your question, not really.
