Possibly Switching

Hi, I am looking at moving to T-Mobile. I currently have Verizon I have 3 Phone lines with them on the Unlimited Plus Plan and 1 iPad on the Welcome Plan and these perks: Disney Bundle which inc’s Disney + Premium, Hulu, ESPN+ & Netflix & HBO Max (with ads) & Netflix Premium & Apple Music Family. I have done zero research before stopping in at a T-Mobile store on my way home yesterday and got 1 quote. So I was told at the store I should sign up for the Experience More 2.0 vs Experience Beyond 2.0. I had told them 2 of my 3 lines are on phone payments but they only have 1 more phone payment and the end date for the bill will be in a few days, So they told me to do the BYOD and collect the 200.00 gift card for those 1st 2 lines and the 3rd line its phone was bought out-right so there is no phone payments so they said the same thing for the 3rd line too. The iPad is also bought outright a while ago so they said BYOD for the iPad too but it only qualifies for 100.00 gift card. Now here is where I am confused they told me they have tons of discounts and options so they wanted to match the right discounts and options to the plan I needed. So they told me I would get Netflix and Apple TV and that I could add the Netflix Premium for 7.00 and Apple TV would be 12.00. Also they told me my 3rd line is free and that I would be best fit for a discount (inside). I did not ask for this they just offered it to me, the store was very busy so did wait for 20 min or so to speak to someone. Also they told me to get this discount I must take 3 Trackers but I have no use for them what so ever, if it is required I am fine with taking 1 but I have no use for 3 as they would be sitting in a drawer. I told them I would think about it and come back the next day, the manger also spoke to me and wrote it all down and gave me his business card. These are the my 4 major concerns 1. The 2 lines that have phone payments they want to upgrade next month once their phones are payed off, but I want to make sure I am one the correct plan so that they get max trade in credits. 2. I was told for the gift cards I would need to wait 30 to 60 days to get them before these 2 lines can upgrade. 3. I asked if I could upgrade in the beginning of next month but they told me the Promos are better now then they could change next month so its not worth waiting and the reason I wanted to do that is that I could claim the final trade in credit for my 2 lines who have phone payments. 4. Do I really need to purchase those trackers, as I have stated above I really have no use for them, I got AirTags which are good enough for me and if its a must is it ok if I just get 1 ? I am sorry if this is long but I am trying to do some research before I sign any paperwork.
