sounds good. shield groups are preferred mainly due to the shield rep happening at the start of the cycle (instant heal) and the armor rep happening at the end (5-6 second heal). But for 10 mans a strong armor gang of 3 logi 7 t3's has no problem. Your ideal shield booster is a Tengu, he gets the most bonuses to shield warfare links, followed by a Vulture and then there's the Drake which suffices but has no bonuses.

As for ideal DPS ships the Tengu is again on the list along with faction battleships such as the Mach and the Nightmare. Here's a great list of fits with various (many many) DPS ships that work well for incursions

I don't think you'll need any sniper fits for 10 mans but i could be wrong.
