Yes, you should SL your SRs to SL4. Each SL on a non-grail SR is equivalent to 3.5 R, so SL-ing up to 4 is equivalent to a 14 R fodder but uses only 9.5 R equivalent to get there, thus gaining you 4.5 R in total.

You can SL FLB weapons all the way up to SL30 by just using SL4 SR weapons. Grails and SSR fodder just makes it easier but aren't actually required.

I always have a lot of R fodder but a limited amount of SR.
Just farm all 18 standard disasters everyday, and you should have sufficient SR. You can farm all 18 expert in addition if you want to speed things up more. As a bonus, STA/EXP farming also drop disaster eidolons that you can orb.

If you don't have enough AP/pots for all that farming, fear not, the AP requirements will drop in a week or so.
