Roster - Waiver Wire Help

I'm in my first league with IDP and we start 2 LB and 2 S.

Scoring: Sack 3, Blocked Punt, PAT or FG 6, Each Fumble Recovered 3, Total Tackles 2, Each Interception 3, Each Safety 2

Currently, my roster consists of:

LB P Willis SF @TEN
LB J Freeman IND vsDEN
S E Berry KC vsHOU
S G Quin DET vsCIN

I recently dropped both B Carter and D Butler for other positions I needed to fill. With Freeman looking like he will miss Sunday's game, would you consider dropping him for one of the following?

A Ogletree STL @CAR
AJ Hawk GB vsCLE
E Henderson MIN @NYG
L Fletcher WSH vsCHI
L Timmons PIT vsBAL

Additionally, should I replace either of my S with any of the following:
Y Bell ARI vsSEA
A Rolle NYG vsMIN
L Landry IND vsDEN
D Whitner SF @TEN

Also, should I try to find room to pick up S L Landry IND regardless of starting this weekend?

Sorry for the newbie questions, I'm still getting acclimated to IDP. ANy suggestion would be greatly appreciated. Thanks!

Freeman is going to play as is Landry, so pick up Landry and play him.
