Sorry.. that was probably a little garbled as answering two things... 1st is to get root access using z4root and then to browse the root directory of your phone using root explorer. You would need this to install market manually as you would need to to place the google applications into /system/app and importantly change their permissions.
you can download the google apps from :
you'll find them in the 'system' then through to 'app' directory of what you have downloaded
you'll need to copy I think 6 files...
Copy them to your sd card then use 'root explorer' to multi-copy then paste them into your /system/app directory. When copied, change the permissions on each by a long press and selecting permissions and select as follows
User - Read and write
Group - Read
Others - Read
restart your phone. Browse through to Vending.apk - tap and install and market should appear on your phone.
Alternatively... just install the latest Le UI 3.5 rom as posted in another thread and all the work is already done
