The Gro Lux is indeed the better one for plant growth, while the wide spectrum has a somewhat higher CRI to make fish and plants look more "natural" as opposed to "enhanced" such as with the P&A and Gro-Lux.
I've never heard of needing any type of special starter. I've used Gro-Lux bulbs in a huge variety of ballasts and never had problems.
So if the Phillips Natural bulb is the same as the GE Sunshine, then it's going to be pretty much identical to the C50. Not a bad bulb, but not quite as good as the Gro-Lux. If you don't feel like hassling with the search, just get the GE P&A, Sunshine or Phillips Natural. But if you find a local Lighting Supply store, you should be able to get some of those Gro-Lux bulbs.
