[Grammar] not to do but to do

[davidtrinh]

Two days ago, I talked about these sentences with my non-native English speaking coworkers during lunchtime. I am going to write them down below.

(1) We are not ready to go to the final step of our project but to present our findings so far right now.

(2) The manager continually leaves work early without permission. His subordinates can do nothing but ignore his irresponsibility.

Is (1) the same as when it's written in full "We are not ready to go to the final step of our project but we are ready to present our findings so far right now."?

Are my sentences grammatically correct? Thanks.

I wouldn't use "but we are ready" again. It's grammatical, but it's too repetitive stylistically.
"We are not ready to explain the final step of our project yet, but we can present what we have found so far."
2. is OK.
