Front end advice please!

My 94 Yukon 5.7 L 350 V8 has had lots of front end replacement due to wear and tear from a 4" lift and 33" swampers and mudding. I need new tie rods a man told me, would I replace inner and outer and all bushings? Will I need an alignment after I do it myself? I am trying to avoid shop help due to lack of $$ these days, I just need to get back on the road. Thanx!
