The first tx in better than the second, but there is FlySky FS-TH9X 2.4G 9CH System which is better than both of them if you upgrade it with an Frsky module.
You can use a 3s 3300mah 25c lipo with 10*4.5 with 20amp esc on 980kv sunnysky motors, if you keep the total weight below 700gms you should get 10-15 mins of flight time maybe more.

Each sunnysky motor consumes 16amp max approx so 20amp esc is enough, however you can still use 25 or 30 amp esc's as it will be better.
To select a battery, you would have 4 motors on your quad so in all approx 80amps current would be required to run all four at full capacity. So you need a battery which can discharge that much current. Multiply the C rating of battery with total capacity(mah) and divide by 1000 and you will have the constant discharge rate of battery.

Be patient.Also read some more stuff anywhere you can find about multirotors and also see this

The first radio is better.
Regarding the battery if you are using the sunnysky motors your current battery should be good enough.
