Is the front suspension on a 98 2wd the same identical as the newer 2nd gen's.
No, it's very different. The front suspension was changed significantly for the 2000 model year. The scrub radius changed, the offset was increased at least 1" (hubs set more toward outside of vehicle), changed over to sealed wheel bearings, brakes went from 1 to 2-piston caliper. Virtually no parts are interchangeable, and since the lower A-arms are different (and consequently the frame mounts changed a little) you cannot switch front suspensions between 2000+ and '99-older Rams (that is what I was told anyway).
Other changes in 2000 was a wider rear axle, added 1" rear spacers, and 265 tires on 8" rims became standard (replacing the 245 tires on 6" wide rim).
The rear leaf spring pack is the same whether or not you have the camper package. . . camper package just adds the overloads.
Hope that answers your guys' questions
PS: Since I owned a 2001 2wd shortbed and now have a '98 2wd shortbed I can compare the two. . . I definitely liked the suspension and the way the '01 handled curves better than the '98. It tracked straighter and was noticeably more stable. The '01 sat a skosh higher, in front and back, I like how the '98 sits better.

Pic of '98 with suspension untouched, I think it sits a little lower even with 17" wheels
