I think all of these were already answered, but this one needs to be stressed.

No. Do NOT farm the "Caladbolg" from the Exchange Shop. For some retarded reason, all SR weapons from there have PITIFUL stats, and you'll be sorry if you farm those.

For the same amount of effort, you can probably farm two LMB Disaster Assault SRs. Yes, leveling them up is highly recommended. Skill level those up to... let's say 10 slvl each, and then start working your way up from there.

Considering how new you are, I doubt you can hold a candle against even level 80 Ult. Do you mean total?

If you're at a total of 160 Ult, just keep at it. You're going at a fine pace. Final rewards are at 400 Ults. As long as people keep farming Grails and Ults, you'll reach the goal barely in time I think.
