Do we have a Veteran Sharepoint User that could answer questions periodically or guide me to good resources they have used? Especially with Sharepoint Designer

[Sharon D]

I'm learning SharePoint on the fly (aka short timeframe) and I'm needing some pointers and tidbits here and there.

Can anyone point me in the right direction to get a jumpstart on using SharePoint Designer 2013? There are so many videos out there I could sink. Thought maybe someone would have a person they would recommend following OR is there maybe a quick read book (are the Dummies books any good for learning SP Designer?)

I got thrown into this without any knowledge of permissions, hierarchy, design, using the tool/app and it's all due yesterday. My boss is aware I am teaching myself and has been patient but under a time constraint. 

Luckily I know some html from wayyyyyyyyyy back so that is how I am have been editing the SharePoint page; from what I understand it's online (but some things might not be). Hoping the SP Designer will help speed things up if I can get a quick start guide/video/book.

Any help is appreciated!
