Mac Running Slow - Etrecheck attached - Pls Help!

Question

Hi,
My Mac has been running painfully slow recently. This all started when i had almost used up all my memory. I purchased a hard drive and copied files over to create more space, however my Mac is still running slow. I get the beach ball all the time when trying to do most things which is frustrating. I use Logic and Serato on my Mac and never had a problem before the start up disk got full! I thought by removing data it would resolve the problem but it has not. When i updated to Mavericks my Mac was running fine as was Logic.
I have done a Etrecheck and attached below to hopefully shed some light on the problem.
Please let me know your thoughts? All help is appreciated.

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
