n00b wheel size decision help

[Nibs]

hi guys I've been reading up alot on this site about everyone's wheels and tires. I have an 07 LB with 14"OEM wheels. I'm ordering some wheels online and can't decide between 15 or 16s. After talking to a guy in a local shop today he tried to hook me up with a package for 17" rims and 215/40R17 tires saying this is the best size tires for 17". After checking the tire guide here that doesn't seem to be the case. It's not even on the sheet for the non RS model. Though I have seen some garages here with them on...

I've never bought aftermarket wheels before so I'm a noob. What I'm looking for is the most width really.... according to the tire guide sticky here if I go for 15" rims I should get 205/50R15 tires to get closest to OEM. If I go for 16" I should get 195/45R16 which are only -0.21%. Even though the 16" wheel is 7" wide would it be wider with the 195 tire then the 15x6.5" would be with the 205 tire?

is the 205/45R16 tire ok even though its a 1.34% difference? I think this one would be the best being 16" and 205 wide

Am I just completely making this decision way harder for myself then it really is? keeping close to OEM seems to be the biggest thing...

I'd appreciate any feedback in helping me with this decision. thx
