upgrade macbook pro hard drive early 2011

Is it advisable to have a complete copy (e.g.

to the SSD once it's installed in my MacBook and the OS is up and running, from the Time Machine back up?

My main concern, however, is whether I will be able to migrate my Documents, Photos, Videos, etc. I have heard it is better to do a clean install of the OS, and I do not mind installing all 3rd party apps all over again. I back up via Time Machine to an external hard drive.However, I do have a couple of questions before the upgrade, to which I could not find relevant answers to. I will not be doing the upgrade myself - I'd be too stressed that something won't work out - so I decided for Apple Authorised Technician to do it for me (they have 3 options available: 1) install the SSD, 2) install the SSD and install the OS and 3) install the SSD, install the OS and copy all the data from the HDD).

I have upgraded my RAM to 8GB a couple of years ago and thought it is about time to do the SSD upgrade as well. I am currently looking to upgrade the HDD in my MBP 13' Early 2011 (running OS X 10.9.5) to an SSD and I have settled on Crucial MX200 500GB SATA 6Gb/s 2.5' Internal SSD.
