I went from MTL to DTL in and around the 5 month mark! Perhaps it was because at the time, I felt I was able to do 'less' with the MTL devices; higher resistances etc, and the options for DTL were better such as RDA's, Subohm vaping, etc... it was a bit more exciting. This might have totally changed in this climate of hardware saturated market.
Terminology will come with time, you will understand the more you get into vaping. Generally, the lower the value of ohms, the more suited to DTL vaping... but that's a big generalisation! 1 Ohm, as already said, would be fine for MTL, even as high as 1.2 might also be OK for you.
Regardless what anyone here recommends, the answer is usually always - 'Do whatever it takes, and purchase whatever you need to STOP smoking.' - I guarantee you will find something somewhere that suits what you like, including eJuice!
Have you gone to a 'proper' vaping shop? (not a national one hat sells the stick ecigs with crappy ejuice etc), but a locally owned one staff who are enthusiasts with a load of devices you could try out and recommend?
