vias connect fine to pours
i do it all the time touch or place the via on a grounded pin or pad, then drag onto pour
if you place them initially directly on the pour sometimes they pick up the ground net and sometimes they don't
sometimes just wiggle them on the pour and they pick it up
not as much of a bother as it sounds
and/or select them and global edit the net name to 'selected same'
nothing wrong with your named free pads method though, we do that sometimes too

Vias don't connect. Convert them all to free pads. Give them all the same designator (98, 99, etc.), then you can make unique rules for connect style (solid, etc.).
TQFP - probably clearance rules. The space between the pins, along with the track width of the polygon lines and/or the clearance rule won't allow a connect. Adjust the settings, or draw a trace to a (similar) free pad.

Well, this is weird. I have GND polygons on top and bottom layers of a 2-layer board. Very standard. To fulfill connectivity, I drop vias (35/28mil) around to join the two planes, and as expected, they pick up GND as their net. Then dbl-click the planes, select each one, and have it rebuild.
The vias are isolated.
They're definitely in the GND net. So are the planes. The Polygon Connect Style rule is set to Relief-Connect, using 90deg 30mil tracks.
I know this is something simple, but it's eluding me ...
Hrm - just noticed, the GND pins on the TQFP chips aren't joining the GND planes either. The GND side of the decoupling 0805 caps are joining just find though. Ah, got that one figured out - the relief traces are too big - changed it from 30mil to 20mil, and now they join.
But the via are still isolated.
