Excel into grasshopper via Lunchbox

i am trying to create a system for producing .DXF files to laser engrave serial numbers on components

i have sucessfull routed Excel into Grasshopper using Lunchbox and managed to filter the data that i require, but i have a few glitches that i am struggling with ?
or maybe i am going completly down the wrong path?

1 i would like to align the 3 lines in Rhino Centeraly, not to the left hand side
2 i would like to change the font to Avenir
3 i would like to take the serial number from the botom box to make the file name and save it as a .dxf

any help or pointers would be apprecicated
