The eve uni page is accurate in that your peak recharge rate (around ~30-50% shield) is larger than the rate at max shield. However, I am 99% sure that the rate shown in pyfa is your peak recharge rate, not your nominal one (the nominal recharge rate is pretty useless as a piece of information).
A myrmidon cannot tank 1400dps. However, you can make a fit that will tank all the combat sites. The relic sites are generally considered to not be worth the hassle any ways. Or at least they were back when I was in a wormhole…
Finally, drone boats are indeed tricky to use in wormholes. A gila might actually do better with the super-drones while still being possible to fly as an alpha.
