5100 help for a noob

ok here goes with a lot of questions , hopefully this is in the right place and someone can help me out with 1 or 2 . bare in mind ive only got the infa red connection at the minute though .

1 , i was using oxygen II to upload ringtones but they went into the actual ringtones menu 4-5-2 instead of my gallery . is there anyway to delete these as 2 of them dont work and the other ones complete shite or is this like older nokias were theres space to hold a couple tones and theyll just get overwritten if anymore go in . i dont really want to try it and hog even more of the memory i have without knowing .

2, is it possible to totally erase the memory on the phone of added items with out damaging the actual software like an eeprom reset on the t100 via a code typed into the handset , not just a factory reset ?

3 , can i flash new firmware with the infared ?

and finally

4 , what are the best programs to use to edit the phoneook tones logos ect mobimb 1.2 doesnt detect the phone for some reason , logo manager fails to send after detecting it and i wanna stay away from oxygen after the f#@!*d up tones .

any words of wisdom would be fully appreciated .
