Use HTTP Request samplers with different contents each one inside an If
Comtroller
- If Controller ( '${keyword2}'=='' )
+ HTTP Requet WITHOUT keyword2 template
- If Controller ( '${keyword2}'!='' )
+ HTTP Requet WITH keyword2 template

Have a look in HTTP Raw Request (JMeter Plugins component) and
*FileToInclude:* marker

Using absolute paths are not a big deal. Standardize a root path using a
property (and capturing it as a variable in your Test Plan) and put all
files inside this folder.

Use the
__CSVRead<http://jmeter.apache.org/usermanual/functions.html#__CSVRead>function
instead of CSV Dataset Config component.
