I agree there is no need for limiting straps unless your shocks extend way to far.
In regards to the driveshaft I would definitely recommend a new one. I went with a Tatton and am very happy with the quality.
x2, your shocks are your limit straps in a sense. Most twin and monotube shocks designed for the lifts won't extend to the point of needing limit straps. Most of the time, you see the straps used when people get to coilovers where the ratio of uptravel/downtravel can vary greatly and may require limiting straps.
