Most beginners seem to want to start with "cigalike" type (small stick style batteries that closely resemble cigs) Personal Vaporizers (PV) and almost always end up upgrading to a larger battery within a few weeks
try to find an ego style VV (variable voltage) battery in the
900-1100 mah range (mah is how big the battery is and how long the charge will last before needing to be recharged - 2 are recommended - one to use while the other is charging) or the Innoken VV3 (800 mah but can be used as a pass through (you can use it while it is charging))
for the eliquid delivery get a good clearo or tank - these are available in bottom coil (better wicking but a cooler feeling vape) or top coil (warmer vape but need to be inverted or "twirled" to keep the wicks working properly - very easy to get used to)
as far as eliquid is concerned if you smoked quite a bit you will want to start in the 18-24mg range
I don't recommend flavors as that is subjective to every individual but if you are looking for an eliquid that tastes exactly like a cigarette you will be disappointed - there are some that are close but hardly ever are they exact - go for the non traditional cigarette flavors and embrace the fruits and dessert flavors (I snacked less when I started vaping)
Nic absorption with vaping is slower than with cigarettes so don't expect an immediate nic "buzz" like you get with cigarettes (vaping = larger nic molecules = slower absorption - smoking = smaller molecules with nasty additives = faster absorption
hope this helps
