Disaggregate the original multipart polyline (Objects > Disaggregate), then examine each constituent polyline and ensure that the ends are snapped to the adjacent line section so that there aren't any gaps. Finally recombine the polyline parts (Objects > Combine) and convert the result to a region.

WMS Publishing – How to Publish MapInfo Map as WMS using QGIS and GeoServer

Two options come to mind

Stick with Geoserver and export the styles from QGIS as SLDs. SLD is supported by both QGIS and Geoserver.
Use QGIS Server instead of Geoserver and publish your QGIS Desktop project directly.

If I understand you correctly, you already converted all styles from Mapinfo to QGIS. Otherwise you could have tried Nathan's Mapinfo to QGIS Style Converter.

[GIS] How to Create Line Feature using two separate point features in MapInfo

Let's assume your tables are called TABLE1 and TABLE2 and that your ID column is called ID in both tables.

'First you need to create a new empty table for the result
Create Table TABLE3 Using TABLE1 File "C:\Table3.tab"

'This tables should also be made mappable
Create Map For TABLE3 Using TABLE1

'Let's specify the coordinatesystem to use
Set CoordSys Table TABLE3

'And now we are using SQL to extract the necessary data from the tables
Select TABLE1.ID
   , CreateLine(CentroidX(TABLE1.OBJ), CentroidY(TABLE1.OBJ)
        , CentroidX(TABLE2.OBJ), CentroidY(TABLE2.OBJ)) "THELINE"
    From TABLE1, TABLE2
    Where TABLE1.ID = TABLE2.ID
    Into __TO__BE__INSERTED NoSelect

'And now let's insert the result into the new table
Insert Into TABLE3
    (ID, OBJ)
    Select ID, THELINE From __TO__BE__INSERTED

Notice that I'm create a derived spatial object - the line - and giving the "column" an alias in the query: THELINE.

I can then refer to this derived spatial column when I insert the result into my new table.
