honestly it wouldve been better if you chose a different starter cause you actually can get chespin later on but no harm done as with future releases ame has promised to add all starters pre e4 so not a big issue.as for the team numel in reborn is a specially great pokemon and i would recommend getting meowstic(just evolve your espurr) as well as a makuhita(evolve both of them pre 2nd gym) and dropping klink as it would only be really usefull after it learns shif gear which your no where near at as well as drop gulpin and go for trubbish instead or even ekans as trubbish toxic spikes can be a game changer here and arbok is generally good early on as for wingull it does learn mist which can negate nearly all feild effects which is a helpfull tactic with the 3rd gym but for now box it and try going for emolga later on which you can get after second gym and is very helpful as for now qualdin hariyama numel and trubbish/ekans can handle the second gym if your feeling unsure soon you will gain access to some pidoves evolve it can be helpfull
