You only need 1200 kT of cargo space for the troops. That leaves plenty of space on the breathable worlds (especially if you take Advanced Storage Techniques). Mines are small. You can fit tons of them on a planet. Also, build a storage base or two to hold them (and those satellites

). WPs and Satellites are useless against even moderately sized fleets. They might damage a couple ships, but that hardly means anything, as you should always have some repair ships along with your fleet. They are cheap. Especially when you get to higher speeds, the ships can usually do a lot of damage to the sats/WPs before they get a chance to fire. Their range advantage is not enough, esp. since WPs can be hit very easily from long ranges, due to the -200 ECM penalty for planets. I hardly build them past the early game. Better to spend resources on colony ships, and warships to take the fight to the enemy.
I have only been slowed down by WPs once past the early game, and that was when I attacked a planet that had been filled with temporal WPs with a fleet of about 50 primitive LCs and CRs (they had mostly DUCs, with some PPBs). But, that did not help them much, as I had plenty of state of the art BBs coming on-line at the same time, and they had already lost a lot of ground. Other than that, my fleets have always been able to overwhelm planets filled with WPs. They are really only a threat in the early game, and partially into the middle game.
