The Talmud tends to have a wider idea of what Torah is about than what you see in Maimonides. For example we find Hillel II said there would not be a messiah (ever) because the King of Israel Chizkia fulfilled that role. And in the Gemara that discuss the opinion of Hillel we do not find anyone accusing him of being an apikorus or heretic. Now we know that the belief in a future messiah is one of the thirteen main principles of faith that the Rambam derives from the Talmud. And it is a clear principle to him that anyone that denies or even does not believe in any one of those thirteen principles is a heretic and not even considered Jewish.
This I do not mean as a question because it is clear that there are other opinions in the Talmud that hold belief in a future messiah is important to the degree that the Rambam stated. And all the Rambam did here is to decide the law as is his usual custom.
My point here is really meant for Reform and Conservative Jews to realize that not only is the Talmud important for them to learn but that it also represents a world view of Torah that is closer to their own understanding of Torah than Orthodox Judaism. This is in spite of the fact that the Orthodox do try to represent their position as being supported in the Talmud. Most often this is simply not the case.
On the other hand there are positions in Maimonides that are closer to Reform Judaism than what seems to be so in the Talmud. Secular studies in Natural Science would be the most famous example.
In a highly ironic way I discovered the position of several medieval authorities concerning secular studies when I was trying to find Chizuk [encouragement] about just sitting and learning Torah all day.
This happened when I started learning Musar (Ethics) and discovered a good amount of the medieval Jewish authorities were basically saying to go out and get a job and do not use the Torah to make money and also to learn secular subjects. This was the exact opposite of what I wanted to hear from Musar (Ethics) books.
[I thought that sitting and learning Torah was the ultimate goal.
On the other hand we all should learn Torah and do mitzvot as much as possible. And the Reform are wrong for trying to redefine mitzvot into social activism. That is intellectual dishonesty. Mitzvot are mitzvot and averot are averot [sin is sin] You don't get to redefine these things according to your sexual or intellectual orientation.
