Mavericks install incomplete. No Apple installers on HD. Will I be able to upgrade to Yosemite and will it fix all that didn't install with Mavericks upgrade? Very slow connection speeds 30 hrs to download Mavericks. Tried re-install; no help/

Question

Ever since upgrade to Mavericks I have been having problems which are too numerous to mention. I finally found a program from a UCBerkley professor called Pacifier which indicated 4000+ of 400,000+ files and folders did not install. I was unable to go further to try to fix everything because Pacifier can't find ANY Apple installers on my HD. It recommended I download the Mavericks installer without reinstalling to continue; however, after having done so (very slow connection; takes 30 hours to download) and although the installer appears in apps while downloading it disappears and NO Apple installer packages can be found on my hard drive. I tried to download Yosemite once and it indicated my system wasn't eligible for the upgrade. Its' download time was similar to Mavericks; 28+ hours.
I am using a Macbook Pro mid-2012 version OS X 10.9.5 (13F34); Processor 2.5 GHz Intel Core i5; Memory  4 GB 1600 MHz DDR3; Graphics  Intel HD Graphics 4000 1024 MB.
Regardless of how many files and apps I remove my memory is being eaten up to the point I can hardly do anything at all. There are no civil words for how frustrated I am. Someone please help me.
Thanks,
JJ

Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.
