Switch the order in your process to 1., 3., 4., then 2. i.e. bung/spund (Is that what you mean by shut-in?) 1 -1.5 degree P. above TG. Crash cool when TG is reached. When cold, harvest yeast for repitching or disposal. Pull yeast daily for 2 - 3 days.
>5) (wait 2-3 weeks) transfer to serving tank
Drain yeast twice just prior to final transfer. There won't be much at this point.
If you truly have 2 - 3 weeks prior to transferring to your serving tank the procedure described above will give clear to bright results, again given a yeast strain with M - H floc. No opening manways on "finished" beer, no mixing (which can both be sources of contamination), no de-gas/re-gassing, and with practice a cleaner, better end product.
