Will this tuned to low 153.410 and high 158.115

Thanks for your concern on this item. You need just access https://www.amazon.com/dp/B07VLSPZLW/ then Clik "New(2)from", and choose the last one "ships from DotDotTech".We can tune and ship this product from China to meet your requirement low 153.410 and high 158.115MHz.

What is the minimum frequency spacing?

The minimum frequency spacing is 4MHz. The customized spacing range of this unit is 4-7MHz, and we recommend 5Mhz frequency spacing for the better performance.

Can the offset be tuned to negative 0.6 mhz (e,g, 144.750 rx, 145.350 tx) for 2 meter (144-148 mhz) ham repeaters?

Specs show it needs 4 MHz separation so it would not work well for 2 Meter ham that is .6 MHz offset.
