Two Questions

(1)
After repairing a puncture recently I noticed my tyre (which is directional) was put back the wrong way. Will this make any noticeable difference to rolling resistance and wear on the tyre.

(2)
The same wheel when put back seemed to be binding a little when I spun it, so I slackened the quick release nut a little and it spun forever. However I didn't feel comfortable with the amount of weight on the skewer for safety reasons. Is their any set procedures for the amount weight one puts on or is it just guess work. Don't get me wrong it isn't slack, I would just prefer it to be harder to close,but as I said if I do, it doesn't spin as freely.

OK, questions 1: Unlikely to make much difference. Direction of rotation may make a difference to grip when cornering or in the wet.
Q2. The QC Skewer doesn't take the weight it just holds the hollow axle in the right place. If the wheel doesn't spin when the QR is tight it suggests that the cone nuts on the axle are slightly too tight and should be backed off slightly so that you can lock the QR tightly without it causing the rear wheel to bind.

Cycle tyres are not directional because the tread pattern is nothing but a pretty design, it has no effect on performance (Assuming road bike tyres, aggressive treads on MTBs may be different).

And even with cx/mtb, the rear tyre should arguably be on "backwards" to improve traction.

^^^^^ +1 for braking traction, its how I fit all mine.
