Hello Irene.
For the "Grand Tour" at 10am you visit Liberty Square (where you start), you walk through old Tbilisi seeing some of its buildings like Jvarismama church, then Abanotubani area, you see the Metekhi church with Gorgasali's monument, cross the Bridge of Peace and have a view from Rike Park (where you have the cable car). But you don't take it (even though you could do it at the end of the tour not knowing what's all about). You access the botanical gardens by taking the cable car so the answer to your question is no. They also do not visit the Trinity Cathedral.
With the tour starting at Fabrika hostel you'll see more of the history during Soviet Times.
It's an introduction to the history of town (in both cases) so those attractions you're asking for you'll have to visit on your own. The visit to them would always take more time than they have in a walking tour.
Cheers!
