Why would you say "No. Lo compré yo"
It seems to say "It I Bought I". I am finding a few things in the grammar hard to understand. Why would you say "Lo" first and not " Yo compré Lo"?

Someone is saying,
"No. I bought it. Me.
The 'yo' at the end is added to emphasize that 'I' bought it - not you or anyone else. This probably makes sense in the context in which you saw this.
As to the location of 'lo', the direct object (almost) ALWAYS precedes the verb, unless the verb form is in the infinitive, gerund, or imperative. But that will come later.
Unless the verb is in the infinitive form, the pronoun goes in front of the verb.
For example, if I were to use the ir + a + infinitive in your sentence it could look like this:
Yo voy a comprarlo. I am going to buy it.
Or like this:
Yo lo voy a comprar.
So, if it's in the infinitive, it can go in either place.
Wow! this is tough stuff, so I really need to understand the way verbs etc work in the sentence structure. Will it become easier as I progress? On the Rosetta Stone course it doesn't help you that way, so at times its hard to really understand why its written a certain way. Are there any guidelines to help? I have worked alot of things out but as the course gets more difficult, Its not so easy and I need to understand how to make sense of the grammar.
You need a good grammar book - preferably in your own language for when you are in the early learning stages. It is not easy to learn just by listening - you need to know how and why things are formed as they are. And of course, the reference section and lessons on this site are excellent.
To find them go to Learn Spanish at the top of the page and More where you will find everything listed.
Good luck!
