New PC from scratch just ordered

[omaigawd]

I just ordered all my parts for a new Intel Gaming PC. There are several things that may seem abnormal about this build:
-Rosewill V2 Thor Black Case
-MSI Gaming Z170A GAMING PRO LGA 1151 Motherboard
-Rosewill Photon Series 750w Full Modular Power Supply
-WD Black 1 TB Performance Desktop Hard Drive
-Corsair Vengeance LPX 8 GB (2 x 4 GB) 288 PIN DDR4 RAM
-ASUS Geforce GTX 750 Ti 2GB
-Intel Core i5 6400 6M Skylake Quad-Core 2.7 Ghz LGA 1151 65 Desktop Processor

I have a several questions as this is my first PC build.
-I'm planning on upgrading some time soon in the future. Would a i7 6700k and SLI GTX 970 be okay with the current power supply?
-Will the processor be a bottleneck for the GPU while gaming? Both are fairly low end but I just plan on 1080p
-As this is my first purchase on Newegg, how would a delivery like this work? As that many PC parts (and even a monitor and some add ons not mentioned) take up quite a bit of space, how would it be delivered? Would it just be dropped off at my doorstep or would there be a required signature? What would happen if I weren't home at the time of delivery?
-Would this be an upgrade or downgrade from an Intel i7 3630QM (a mobile processor, so I'm not sure) Although I feel it may be a downgrade I'm not too informed on the difference between desktop and mobile parts.

Hey omaigawd,
Hey so, nice build. No worries and yes an upgrade to a 6700K and SLI 970 is a great choice, it would be also no problem with the current PSU.
No the processor, both either the 6400 or the 6700K. There won't be any bottlenecks by processor, either of them.
It would be delivered with normal packaging in a couple of days after ordering. It would probably be just dropped of at your doorstep, but I have little experience with newegg, as in deliveries. Sorry.
This would all be an upgrade, so don't worry. The mobile parts are about 1 (The new GTX980 desktop GPU in a laptop is why it is a small gap) to 70% difference, but normally, without the new gtx 980 in a laptop it would be between 30-70% difference. So this is all a great upgrade.
