I'm not going to go between the references you've quoted, I'm just going to respond here. Portions of this response are indeed from Catholic Answers, with my own additions and elaboration throughout.
Faith is only possible with grace. Salvation is only possible with Christ, and his death on the cross purchased for us the graces required for the completion of salvation. Our initial forgiveness and justification are not things we "earn" (CCC 2010). However, accepting Christ and faith in Christ does not remove from you completely, the ability to sin. This journey to complete holiness is an ongoing process. It is not measured in time, but by grace and their works. Jesus is the mediator who bridged the gap of sin that separates us from God (1 Tim. 2:5); he bridged it by dying for us. He has chosen to make us partners in the plan of salvation (1 Cor. 3:9).
Jesus said it is not enough to have faith in him; we also must obey his commandments. "Why do you call me ‘Lord, Lord,’ but do not do the things I command?" (Luke 6:46, Matt. 7:21–23, 19:16–21).
The resources you quote cannot be made to mean "we earn salvation". They talk about graces afforded by us through works. Yes. And these works are only possible with grace. Grace precedes Faith, and either grace or faith precede any work God would consider "meritorious". The preceding Grace is a gift, and unearned.
I think it's fair to note that CCC 2010 does not say that we earn salvation. Quite the contrary. It says that we merit graces. This is different, though these graces may lead to the completion of our sanctification. I understand the perception of various protestants on the subject though as I used to be one.
Again the Quote from Trent Session 6 (canon 32), is talking about an increase of Grace.
Again, the council of Orange says very clearly "The reward given for good works is not won by reason of actions which precede grace, but grace, which is unmerited"
"The last canon basically forces Catholics to reject the notion that works are just the outworking of a valid faith (Protestant position), they are not "merely the fruits and signs of justification obtained." You seemed to saying you believed close to that."
I do believe that what perhaps if I'm understanding you correctly, you would call "mere outward signs of faith" can indeed be more than outward signs of faith in that performed through grace (we should still be agreeing thus far) they also merit grace. I think the scripture for our work meriting graces is sound. This is of course if you understand the broader context of Holy Scripture as opposed to citing a handful of individual passages.
