Do I have any options?

I've searched high and low, thru these halls as well as

anywhere google,bing,ask,digg,yahoo,and anyone else

patient (or bored!) enough to lead me, and still no

concrete answere.
I don't think it would be a good idea for me to root my

phone, as it took me a few hours to learn what "root"

was, the pros and cons, and read thru several how to's.

I'm just not computer literate enough yet,(but am a

very fast learner!) and because of that would not only

run the risk of screwing it all up, but the advantages

of rooting would be wasted on me as I wouldn't know

what to do with it.(kind of like handing a carpenter a

multimeter!)

With that in mind;
1) Is there ANYthing I can do to increase my internal

memory?(I already clear my caches every night,kill

everything I'm not using,auto nothing...basically

everything in the noob guide)
2) Will installing and using the "openhome" app and

theme pks mean I won't be able to take advantage of

utilizing many other apps and widgets? (I currently run

12 apps+bettercut and have currently 53MB available)
3) I understand bettercut doesn't work with openhome,

but am I right to assume that I won't need bettercut

once I've installed openhome?
4) Do most open home users (that are NOT rooted) have

openhome installed always, then download a theme, use

what they want, then uninstall the theme?
Thanks in advance for any insight!
