For centers, try to lookahead to as much of the first one (and possibly even the second one) as possible during inspection.
For edge pairing, are you using one at a time? If you are, then this:
When you are solving an edge pair, look at one of the wings
next to one of the wings you're pairing. Then, while solving your edge pair, find the wing that goes with that one. So basically lookahead. Just try not to pause as much. Hope this helps.
